Seam-sealed, completely waterproof, and warm as stovepipe, the suede upper and handcrafted rubber shell are lined with a 9mm felt InnerBoot for a temperature rating down to -40° below zero. Removable, washable and made from recycled felt, the InnerBoot is topped with a Sherpa Pile™ snow cuff for a classic look that’s both very warm and easy to care for. And where the rubber meets the black ice and snow-covered road, a low-profile herringbone outsole provides grip without tracking up the mudroom.
