The enhanced comfort is obvious, but the main reason is actually performance! After 20 years of working with World Class athletes, we're convinced that it's imperative to still allow the foot to adjust and balance naturally when providing support. If your foot is over supported due to overly hard materials, you tend to lose "touch" and "snow feel". More is not always better when it comes to foot support in athletic footwear!

Yes! We think the ultimate validation of our insoles comes from their use by all levels of athletes: weekend warrior through world recognized competitors. Since we don't pay anyone to ride our insoles, it's not kosher to advertise their names and faces. However, we're very confident in stating that DFP's are widely used by top athletes in all winter disciplines: alpine, freestyle, freeride, snowboarding, nordic and nordic combined. Those insane guys that ski off cliffs in wing suits? Them too!

Yes, due to the insoles being flexible, they work very well in other footwear.

Around 5 years is typical depending on use. Some are still going strong after 10 years.
