Professional Chambord Pro Iso boots are ideal for cold weather. In their Iso version, they are lined on the inside with 3.2 mm thick neoprene. Neoprene is a reference in terms of insulation, it contains microscopic air bubbles to better insulate from the cold and maintain the temperature. With their rubber outsoles and their unique double sole profile, they adhere to all types of terrain: bevelled lugs provide grip on soft ground and the anti-slip creases adhere to industrial surfaces. They are long wearing and durable for heavy use.\nThis rubber boot is handmade in France by our master rubber craftsmen.
