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 gender-specific, asymmetric ActiveFLEX binding, featuring patented Control Wings, provides lightweight control, support, comfort and ease of use. Men?s binding fits up to size 13 boots, women?s size 5-11. * The Viper 2.0 carbon steel toe crampon?s jagged tooth construction maximizes weighted traction and responsiveness. The aggressive tangs in the toe crampon are concave to give the crampon a scooping function in soft snow.
