The Tubbs Flex NGR Snow Shoes are designed to keep you safe in packed or variable snow. They can also hold men up to 90 pounds on powder. The ergonomic comfort design includes patented Soft Strike Zone to act as a shock absorber and reduce the "foot slap" noise. It's like a midsole in your athletic shoes. These snowshoes have a biomechanically designed Flex Tail, "set and forget" 180Flex bindings, and Flex series 3D-curved Traction rails to maximize weighted traction and responsiveness.
