The Woodwalker series uses the All-terrain Gripper 2.0 sole, known for its excellent grip, even in the lower shaft models. This, combined with the midsole construction, makes the Woodwalkers a functional package for outdoor use. - Standard fit - Unique "Coil lining" material helps to wick away moisture from the boot's structure - Shock-absorbing and heat-insulating midsole resembles more of a running shoe than a simple rubber boot - The outer material is a high-quality and durable G1 70 rubber compound - Pull loops make the boots easier to put on - The heel has a separate reinforcement that makes removing the boots easier The manufacturer recommends this boot for temperatures down to -20ºC, but due to the significant variation in how people handle cold, this cannot be considered a guarantee for everyone.
