The cold doesn't stand a chance with these insulated adidas Terrex hiking shoes. COLD.RDY technology ensures warm feet and comfort, while PrimaLoft® synthetic insulation keeps you warm in negative temperatures. The Traxion rubber outsole provides optimal grip on icy terrain, and the Velcro fastener makes them easy to put on and take off. Made with recycled materials, the upper has at least 50% recycled content. These shoes feature a regular fit, synthetic & textile upper, and a rubber sole. They are small fitting, so you may require a larger size. Please try footwear on before returning to ensure correct sizing as box or label may show US/Euro size.
