A durable, lightweight multi-sport boot built to take on rugged cold-weather conditions whether you're heading up the mountain or downtown. This product was designed without any PFAS (Per- and Polyfluorinated Substances), also known as 'forever chemicals'. Instead, we use a DWR finish that allows your gear to repel water without harming the environment. Features Omni-Grip non-marking traction rubber, Techlite lightweight midsole for long lasting comfort, superior cushioning, and high energy return, Cordura textile, and Omni-Tech waterproof breathable construction with 200g insulation. Please note: Laces and zippers incorporated in Columbia footwear are not waterproof.
