The patented FLEX Tail technology allows the snowshoe to roll more naturally underfoot from heel strike to toe off. The FLEX Tail absorbs shock from the initial heel strike, reducing the amount of stress on ankles, knees and hips. * Tubbs? advanced Torsion Deck design adapts to variable snow conditions underfoot. The deck allows torsional articulation throughout the body of the snowshoe, enhancing traction, biomechanics and comfort on uneven terrain. * The molded QuickFLEX binding is gender-specific with patented Control Wings to center the boot. A dual-pull strap system secures fit while a cinch pull strap makes entry and exit easy. * The 3D-Curved Traction Rails ensure superior side-hill grip in hard-packed and icy conditions. The curved shape helps prevent fore-aft slippage on steeper terrain by avoiding the ?saw blade? effect.
