A protective abrasion-resistant rubber toe cap shields the forefoot. 100% recycled laces and webbing, 100% recycled fleece lining (interior warmth), and 100% recycled mesh footbed cover add a meaningful sustainability story. A 5% recycled PU removable footbed and FloatPro Foam midsole deliver lightweight comfort that lasts. Underneath, the Vibram Arctic Grip All-Terrain outsole delivers winter traction across diverse cold conditions. Stack height 28.5/20.5mm, 8mm drop, 5mm lugs. Around 540g per boot.
