Protect and insulate the feet from cold, wet conditions in this calf boot from ToeWarmers. The waterproof leather and polyurethane upper keeps water out and warmth in. The three-layer Warmtex foam insole provides even more warmth. The top layer is made of polyester felt that absorbs moisture, so feet stay dry. Underneath, a closed cell foam adds warmth by trapping air inside the cells. A layer of Warmtex thermal film on the bottom acts as a barrier against the cold and helps retain body heat. Flexible, slip-resistant thermoplastic rubber outsole provides durable traction. Collar may be rolled up for additional warmth or rolled down to show the faux fur lining.
