As a regular inhabitee of places with boot dryers, I found the concept of dragging these around a little pointless. Until, of course, I went somewhere they hadn’t turned the dryers on. Next trip, the Drysure Extremes were in the bag. I’ve only used these in indoor rooms and a garage so don’t know how effective they’d be in the boot of a car overnight.

I ended up using them in ski and walking boots, always overnight, and the ski boot liners were completely dry in the morning – although when I left the inners in the shells there was some damp. Best always to take the liners out.

Drysure Key Facts

Truly sodden walking boots still had a damp exterior by morning. The bags need to be re-activated if you’re drying something as wet as those walking boots. You take the inner silica oxide-filled bags out of the banana-shaped plastic case and either put them on a radiator or apparently pop them into an oven at 100 degrees for a couple of hours.

On suggesting the latter I found Mrs F to be against using the cooker to reactivate ‘stinky ski boot dryers’. “Does it smell of haddock after fish pie?” I retort. But no dice – the Drysures are relegated to the radiator.

These are easily packed (because they fit in your boots, doh), they dry without being plugged in and can be used for all kinds of footwear. The Drysure Extreme pair are currently in my wellies after someone left them out in the snow…

Drysure Active reviewed by the MTB LAB

Drysure shoe drying inserts and are meant to be used in footwear overnight to facilitate proper drying and deodorizing. They’ll not only reduce odor and absorb wetness and control bacteria, but they will increase the longevity of shoe since moisture and bacteria wrecks havoc on the materials and construction of them. Unlike other boot dryers that require batteries or a power supply for functionality, the Drysure technology and design need no electricity, making it portable and safe to use anywhere.

To see the review on their website click here or see below - MTB LAB 


Drysure utilizes moisture-absorbing silica oxide beads encased in a breathable bag surrounded by a plastic shell frame that assists with airflow. The bags will absorb moisture for 7-10 uses before needing to be reactivated, which is easily accomplished by placing the units directly in the sun or an oven at around 212°F. Drysure is 12x more effective at drying than normal air drying so use them for your damp footwear in your locker, the back of your vehicle, your gym bag or cycling duffle.

The average person sweats between 3-6ml per boot/shoe per day, and if not dried out it can be a breeding ground for dangerous bacteria such as E.Coli, Meningitis, and Klebsiella. This combination of moisture, heat and your foot along with outside bacteria and the lack of airflow cause these issues. Using the Drysure system will restrict the growth of bacteria and fungi in your footwear by effectively removing moisture.

They make two versions: the Active model (which we tested) retails for $32.73 and is meant for regular low top shoes while the Extreme model retails for $39.29 and was designed for ski boots and high top hiking boots. You can use Drysure for just about any footwear that gets damp or sweaty, including those meant for cycling, running, training, golfing shoes, hiking, work, skiing, etc.

Since the Drysure design requires no plugs, batteries, electricity or heat to operate, you toss them into your footwear for them to work. Since they’re incredibly useful at drying, it only takes 4-6 hours to dry cycling and running shoes, while the taller ski and motorbike boots will need an overnight standing to be completely dry. After complete drying, your shoes will be odor free and dry, with improved hygiene and reduced bacteria and fungal growth issues.


Remove the Drysure inserts from their PVC pouch and slide them all the way into each of your shoes and leave them in for at least 4-6 hours. If your shoes are exceedingly wet or damp, then let them sit overnight for a complete drying out. The Drysure inserts will begin their work to absorb sweat, moisture, and odor naturally, and when the process is done you’ll have a nice dry and stink free shoe. After 7-10 uses its time to reactivate the silica oxide beads in the main bags. Remove the inner bags from the outer plastic shells and place the bags in direct sunlight or your oven at 100°C or 212°F. When not in use place the Drysure units back into their PVC pouch. With proper care and storage, the Drysure inserts are reusable and will last many years.


After a bike ride, I’d jam them into my shoes and let them sit overnight. Supposedly, they’ll dry the shoes in about 4-6 hours, but I never tested that, since I’m not usually riding twice in one day. I have stuck them in my shoes after they got pretty soaked in a rainstorm, though it wasn’t so awful that I had to pour water out of the shoe before using the inserts. The next day the shoes would be dry and odor free, well at least the shoe odor never reached any high level of stinkiness, just a mild freshness. According to their instructions, you are supposed to place the Drysure inserts back into their PVC pouch after usage since I assume they’d absorb the moisture in the air? Due to the extreme dryness of the Colorado air, I sometimes just left them in the shoe until they’d be required again, meaning they always sat in my shoes. The only come in one size, so if you have small feet the plastic frame might be too long to fit into the shoe properly?

Once the drying process no longer becomes useful, which is usually after 7-10 uses, its time for a reactivation. I always just tossed them up onto my trucks dashboard, so they’d get some direct sunlight, and that would put them right back to a full charge. According to the manufacturer, reactivation can be done by three methods (no microwave):

  1. Put bead bag on a warm radiator, under car heater or other heating devices
  2. Leave in direct sunlight
  3. Remove the outer shell and put the bead bags in the oven at 212ºF (100ºC) for 1-2 hours.

I never performed the oven or heater methods, as a good Colorado sunshine will heat up and dry anything.

Besides removing the moisture from my cycling shoes and decreasing the odor, they help increase the longevity of the shoes, at least internally. All that sweat and moisture and bacteria break down the materials and substructure at a faster pace within the shoe, and although the outside might be getting abused, at least the inside fares better.

Bottom Line

The Drysure shoe inserts are a complete portable drying system, that combat moisture and kills odor in your footwear, and prevents the buildup of harmful bacteria and fungi. It uses moisture-absorbing silica oxide bead bag encased in an innovative foot-shaped plastic shell form that easily slides into the shoe. It does a beneficial job of drying and removing odor and can be used multiple times and reactivated when needed by warming in the sun or an oven.

Besides not requiring any heat or electricity to function, they’re safe, were designed to target moisture laden toe and heel areas, will last many years if used correctly and will dry and deodorize your shoes!

Review of Drysure Extremes By Open Snow, USA

Drysure has been reviewed by OpenSnow which was created by a team of local weather forecasters who are life-long skiers and riders. This is what they had to say about Drysure:

When you ski or ride a lot of days, your boots will get damp, and they will eventually smell. At least, my boots smelled.

Of course, I tried to prevent this from happening by taking the liners out of the shells and airing them out. And also by plugging in heating devices that I placed in my boots to dry them out. Both of these methods do work, but simply air-drying the liners can take time, and also, I would rarely have my boots in a place that was close to a plug, so using electric heaters wasn’t always convenient.

In January 2018, Drysure emailed me to ask if I could test their non-electric boot dryer. I was intrigued. Damp or smelly boots is not my biggest problem, but if there was a product that would help, and that I didn’t have to plug into an outlet, well, I wanted to know more.

Here’s what they look like:

Here’s how you use them.

1) Place them in your boot. Moisture is absorbed by the Silica Oxide beads.

2) Remove them when you want to ski.

Here’s how they work.

1) The beads absorb moisture, much like the little packets that come in a jar of pills or a box of clothes.

2) After 10 uses, the company recommends that you “re-activate” the beads by placing them on a hot radiator, in direct sunlight, or in an over. I put them in an oven for an hour and that worked nicely.

More details about how to use and reactivate the beads:

I look at the Drysure boot dryer as a good maintenance product to use when your boots are damp and need some help drying out and to keep them from smelling.

If your boots are soaked, and you absolutely need them to dry in a short time (8-10 hours, eg. overnight), I would still recommend getting an electric heating device to be sure that your boots are completely dry.

But, for a non-powered product, I think that Drysure does a good job, and it is a worthy addition to my gear list.

Top Five Eco Friendly Ski Products This Winter

Do you worry about the environmental impact of your gear?

Do you want to choose eco-friendly brands but don't know which brands to go for?

If you're just getting ready to go out and enjoy some spring skiing then this is a guide you need to read! We've gone out and found five of the best eco-friendly products from this season, so you can look and feel good whilst you're on the mountain.

We all love winter and we all love snow. Our passion for skiing and snowboarding is something that goes beyond a hobby: it’s a way of life. The idea of a snowless winter doesn’t bear thinking about, but the prospect of our winters disappearing completely is a real possibility. Climate change is no longer a political debate discussed solely by bearded environmentalists and politicians in suits - it’s a conversation that is being held on chairlifts and in après ski bars around the world amongst members of the international skiing and snowboarding community.  

In the UK, we're seeing greater measures being taken towards fighting the battle against climate change, particularly within the winter sports industry. More brands than ever before are beginning to think carefully about sustainability and ethical practices, and how we can all help take better care of our planet as the need to take reasonability over our actions – and product purchases – gains momentum. 

Here’s a roundup of five of the best eco-friendly buys this winter season. 

Van Loon Sport Base Layers

Van Loon Sport

Van Loon Sport is an apparel startup who are developing a collection of layers for season 2017/18 manufactured with zero fabric wastage.

As Creative Director of Van Loon Sport Greg Stidolph explains, “almost all clothes are currently made by cutting out shapes from huge sheets of fabric then stitching them together. While great effort is made to minimise wastage, as much as 20% of every square metre can be left unused as off-cuts. When you consider that every inch of that fabric has been sewn, grown, harvested, washed, combed, spun, knitted, finished and delivered before this point, the wastage is much greater than it looks on the factory floor.”

Capitalising on the latest technology in knitting machines, Van Loon Sport are attempting to remove all that wastage from their supply chain, ensuring every length of yarn is used. “The best comparison I can give is that it’s like a 3D printer for clothes” explains Greg. “These machines take in the Merino wool yarn at the top and, via some very smart code & needlework, perfect garment panels come out the other end. It’s such a neat process - I really see this as the next step in ski layers. I hope once we’ve perfected it, the rest of the industry will follow suit and we’ll see a lot more brands manufacturing this way."

The garments launched at Van Loon Sport’s 2017/18 pop-up shop at Mountain Air, Verbier, so if you're in the area, be sure to check them out. "We call ourselves the future of ski clothing: part of that is ensuring skiing actually has a future.”

Drysure Boot Dryer

Drysure Infographic

Another startup brand with a progressive mindset is Drysure, who create shoe and boot dryers using a unique design that allows moisture to be absorbed from your damp or sweaty ski boots twelve times faster than regular air drying.

Whilst most ski boot dryers use batteries or electricity, Drysure has no power source and can be reused over and over again, making the product a more sustainable option compared to alternative ski boot dryers that typically require electricity. Drysure comes in two designs: “Active” for low ankle footwear like running or cycling shoes, and “Extreme” for ski and snowboard boots.   

Drysure Extreme can absorb up to 10 days of sweat and moisture before needing to be re-activated, whilst Drysure Active has 7 days - meaning the amount of energy saved creates a significantly lower carbon footprint compared to other ski boot dryers.

Founder of Drysure, James Robbins says, “when developing Drysure, sustainability was a key factor both from a practical side and from an ethical perspective. We all love winter and in creating a product connected with winter sports, it was important to me that Drysure should be sustainable.” In addition to providing a non-electrical solution to footwear drying, the product provides a hygienic benefit by helping to reduce fungal growth.

Picture Organic Clothing

Picture Clothing - Snow Jacket - Women - Ticket

Of the more established brands, the new season range from Picture has high recycled fibre content using perfluorinated, chemical-free DWR treatments. In a progressive move, Picture’s factories have all signed an ethical and environmental contract guaranteeing best work practice and wellbeing for their employees - few snowsports clothing companies boast Picture’s environmental and innovation credentials and they are pioneering the way in sustainable skiwear. Founders of Picture, Julien, Jeremy & Vincent say, “When we launched Picture in 2008, sustainable development and conservation of the environment were strong values that we deemed absolutely necessary to bring into the brand.”  They continue, “At that time, we really didn’t know very much about responsible textile manufacturing! But today, our goal is to be fully committed, with a global vision of our products’ lifecycle: design, raw materials, confection, use, 2nd life and end of life.” The new range of Picture Ski Wear is now available in-store and online at Ellis Brigham.

Holmenkol Natural Wax & Recycled Scraper

It’s easy to forget about the lasting impact some products have on the environment and ski wax may not be the first thing that springs to mind.  However, according to the team from Holmenkol Natural Wax, when we ski down the piste, snow crystals scratch at the bottom of our skis and remove small bits of wax.

Holmenkol Natural Wax & Recycled Scraper

Any wax that contains fluorocarbons (hydrophobic additives) will stay in the snow until spring then run off into rivers and lakes, affecting the local ecosystem. Holmenkol have developed a universal biodegradable hot wax bar for all snow types and temperatures that does not use any of these additives and which is fully biodegradable while still fast and long-lasting.

 Ellis Brigham

Their natural wax is available from Ellis Brigham stores and Ellis Brigham also offer their own environmentally friendly scraper made from 100% recycled Greencast acrylic.  


You can get both the Holmenkol Natural Wax and Recycled Scraper from Ellis Brigham.

Mons Royale Checklist Hoody

The final pick for our eco-friendly winter product of the season is NZ-based brand Mons Royale and their Checklist hoody, which itself is warm, comfortable and naturally odour resistant. Engaging merino wool as the main material in their products, the brand is mostly known for making excellent ski and snowboard base layers, but what really makes their work stand out is the factory Mons Royal uses to produce their garments.

Mons Royale Checklist Hoody

The brand employs state of the art tech consisting of the latest German knitting and spinning equipment, with a wool cleaning and combing plant that recycles heat and purifies its water as it goes. Their textile and garment manufacturing plant uses environmentally friendly dyes, and the water used for dyes is processed through a water purification plant to neutralise any chemicals to ensure only clean water goes back into the environment.

One of our stockists, Tallington Lakes Pro Shop, has written a very detailed review of Drysure after using them for 50 days in Vail, Colorado.

Here is what he had to say:

Coming into my first extended period of skiing (a season’s vacation in Vail CO); checking all my gear was up-to-scratch was a massive part of my so called ‘pre flight checks’: new powder skis, new outer shells, base layers, mid layers, helmet and all the other usual bits a week at a time skier needs. It wasn’t until my mother made the point about my boots smelling rancid after a week’s skiing, that I thought “I could be in for a smelly few months”! With the plan to get as many days on the mountains both alpine skiing and touring; it was a problem I was keen to solve.

Vail, Colorado - Drysure Reviewed there.

 Having worked at Tallington Lakes as a boot fitter, I am not keen on using the normal boot dryers. Heating the boot even very lightly without my foot being in the boot to hold the foam in place seems a bit counter productive to the extensive moulding processes that is offered at the Pro Shop; in my opinion. So when I was introduced to the Drysure Boot Dryers, I was intrigued. The appeal of not adding heat to dry the boots perked my interest; and secondly the versatility of them, being able to throw them in a bag on hut trips and have dry boots in the morning after the previous days hiking is a nice concept. After using them for almost 50 days on the mountains I can’t believe how well they have worked at drying my boots over night, at room temperature, and most importantly the odour reduction of my boots. My boots smell fresher after 50 days skiing with Drysure than a week’s skiing with conventional drying.

Drysure works by absorbing the sweat and moisture into the Desiccant Silica Gel inside the boot dryers. This helps to, firstly, dry the boots but also, because the sweat is absorbed, bacteria doesn’t have chance to grow which is the cause of the rancid smell. The rancid smell does not come from the sweat itself, it actually comes from the bacteria breaking down the proteins in sweat. No bacterium also means cleaner and healthy boots, and feet because foot fungi are eliminated.



The dryers are easy to maintain. After 10 or so used you can easily remove the silica pouches from the hard shell and place them on a radiator, or in front of the fire, to dry the Silica Gel pellets inside and recharge the effectiveness of the dryers.

For a relatively inexpensive item, that will easily fit in your boots whilst travelling, I will never fly anywhere without my Drysure Boot Dryers again. The versatility of being able to take them on hut or camp trips, and the effectiveness of the technology,  means that wet, smelly boots are pretty much a thing of the past; much to the appreciation of my mother!
