Self-heating outdoor sandals powered by volcanic technology
No more frozen toes on shoulder-season adventures. CoreWalk uses phase-change material technology inspired by volcanic heat retention to keep your feet at the perfect temperature for hours—without batteries, charging, or bulk.
You slip on your CoreWalk sandals. They're comfortably warm from charging overnight. Perfect temperature for your pre-dawn adventure.
Three hours in, crossing a frost-covered meadow. Your friends are complaining about frozen feet. Yours? Still toasty warm.
Six hours of passive heat without batteries. The phase-change material continues releasing thermal energy as your adventure continues.
Inspired by how volcanic rock retains heat, our proprietary PCM absorbs thermal energy and releases it gradually over 6+ hours.
No batteries. No electronics. Just smart materials doing what they do naturally—keeping you warm without the weight.
Designed for those in-between times when regular sandals are too cold but boots feel like overkill.
Rugged outsole, quick-dry straps, and heating tech built into the footbed. Ready for any adventure.
Limited pre-order campaign: 1,000 pairs at $189 with free shipping. Be first to experience volcanic warmth.
