"Great product! This insole by Superfeet adds comfort and warmth to any shoe or boot. I have used these in my Ice Climbing/Mountaineering Boots as well as my Ski Touring / Downhill Boots with great success. The added comfort and warmth are definitely noticeable with these insoles. A great product that I will continue purchase and use extensively in my mountain pursuits. A+"
"These orthotics are generic but do offer a bot if support. I’m a ski boot or any boot that offers little to no necessary arch support, this will most likely do the trick. It’s also thinner than other products out there, enabling it to fit where other, thicker orthotics will not. Overall, this product will likely work for most people, depending on use. If for ski boots only, it’d still be worth it."
"great replacement for. insoles in my winter shoes. gave me a bump in warmth and great assist with foot bed of shoes."
"I replaced the paper thin inserts of my winter boots. These are warmer, provide more support, and are sooo much more comfortable than what was in my boots. Highly recommend Superfeet for ALL of your boots and shoes!"
"I have insanely flat feet and could never figure out the right insoles for snow activities… have consistently had the worst throbbing pain in my feet using any and all insoles but these helped tremendously. Great support and definitely recommend for flat footers. Used for backcountry, snowboarding, hiking, and just lifestyle use - all around great insole. I use them interchangeably for all my boots. Just make sure you cut them right the first time"
"I added these insoles to my snow larding boots. I need an arch with my insoles and these added the perfect amount. Couldn't be more comfortable and they keep my feet warm all day on the slopes. Only issue I found was cutting the Insole to size was a bit challenging. Less is more, especially when cutting."
"I ride flat pedals on my winter fat bike. I do this so I can ride with standard mid-weight or heavier-weight boots, depending on temps. Either way, these types of boots have poor, non-stiff liners that can leak warmth. The Superfeet - Winter Support offers good stiffness and pedal power transfer. They also seem to leak less heat, helping my feet stay warmer longer in the cold Minnesota winters. I will buy them again."
"This has added great warmth, support, and comfort for my winter Chelsea’s in Ohios cold winters."
"Comfortable and easy to cut orthodic."
"Regarding ski boots, was having foot pain from the stock insoles. Tried the all purpose footbeds first because that's all REI had in stock. They worked well but bought the winter support and is superior. Would highly recommend for comfort and much better price than custom footbeds!"
