The FLEX ALP snowshoe is designed for tough backcountry terrain. This snowshoe tackles steep icy terrain with Tubbs' most aggressive traction yet. The integrated heel lift helps ease calf strain on those long up hills, while the streamlined deck shape makes it very maneuverable in tight situations. 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 Rotating Toe Cord design enables the tail of the snowshoe to drop and snow to shed off the tail, reducing stress and strain. The ergonomically and biomechanically designed FLEX Tail absorbs shock from heel strike, reducing the amount of stress on your joints and allowing you to snowshoe farther, longer and with less stress on your body. Tubbs' advanced Torsion Deck design adapts to variable snow conditions underfoot. The decks allow torsional articulation throughout the body of the snowshoe, enhancing traction, biomechanics and comfort on uneven terrain. Carbon steel toe crampon, ergonomically placed under foot, maximizes weighted traction and responsiveness while 3D curved Traction Rails ensure superior side hill grip in hard or icy conditions. Progressive molded Snow Brakes, on the deck as well as the Soft Strike zone, improve weighted traction. Viper 2.0 carbon steel toe crampon with jagged tooth construction maximizes weighted traction and responsiveness.
