Seam-sealed, completely waterproof, and incredibly warm, the canvas upper and handcrafted rubber shell are lined with a 6mm recycled felt InnerBoot for a temperature rating down to -40° below zero. Should the need arise, the InnerBoot can be easily removed and washed to keep boots feeling (and smelling) like new. And where the rubber meets the black ice and snow-covered road, a low-profile herringbone outsole provides plenty of grip when the going gets slick.
