Connelly's latest creation is the compression molded Prodigy slalom ski. Perfect for little rippers who are learning to ski and tear up the water. Sharp front bevels on the Prodigy ski help it bite in the turns, while a full concave tunnel provides edge hold. A narrow step down tail helps the Prodigy turn on a dime. CAPT fiberglass construction. Closed cell polyurethane resin core. Hand-tuned Acrylam base. Aluminum drop-through fin with foil. The Sidewinder brings Hinge Tech to the masses with the first and only step-in waterski binding at a value price. Pull the lever down, and step into the binding effortlessly. Pull the lever up, and feel the zero heel lift. Lycra lined heel and toe hold your foot snug and secure. Sidewinder Boot sizes: XS(4-5), S(5-7).
