Sandals that think. Sandals that warm.
ThermSole embeds microencapsulated phase-change materials into your soles, using exothermic chemical reactions to generate warmth when temperatures drop below 50°F. Inspired by igloo thermal insulation—trapping and releasing heat actively instead of just blocking cold.
You're walking through a snowy mountain town in January wearing your favorite slides, and you feel your feet staying toasty warm as the invisible chemical reaction activates. You look down and see a faint orange glow pulse through the translucent sole—your sandals are literally heating up in response to the cold.
