What Our Gearhead® Experts Are Saying:"My medium arches never felt totally dialed with stock liners, but these insoles hit the sweet spot. They give me just enough structure without feeling stiff, and the added insulation is a big win for long, cold ski days. Comfort is the standout—my boots finally feel broken in from the start."On long days in the mountains, comfort makes all the difference. That’s why we rely on the Sidas 3Feet US Winter Mid insoles to give our medium arches the support they need. From carving corduroy laps to charging through powder stashes, these insoles bring lasting comfort that helps us stay focused on the fun.The anatomical design matches the shape of medium arches, balancing support with flexibility for a natural feel in ski boots. A cushioned gel foam pad softens impacts, while an aluminum film adds insulation to help keep toes warm when the mercury drops. Finished with a durable, soft top layer, the 3Feet US Winter Mid insoles are the upgrade our feet appreciate every run.
