The Connelly Sync Water Ski Bindings feature Free Flex technology that has eradicated the restrictions traditional baseplates put on a ski. Each boot is set in a supportive yet flexible Exolast and is mounted with our Dual Plate design. The seamless outer shell and removable liner feature a dual lace system that pulls your foot back into the ergonomically shaped heel pocket. There has never been a better connection between you and your ski. Connelly Sync Water Ski Binding Features:-FREE FLEX CONNECTION: Wide mounting points transfer energy more efficiently, reducing the amount of torque needed to turn your ski on edge.-DUAL PLATE: Single metal baseplates create a dead spot, limiting the intended flex pattern of the ski.-FREE FLEX SYSTEM: The Free Flex plate system on the Sync binding does not reduce the natural flex of the ski.-EXOLAST SUPPORT-Our Exolast frame is the key connection between the upper boot and the Dual Plate system.-HEEL POCKET: The ergonomically designed heel pocket cups more of you heel bone, drastically reducing movement. ATTENTION! THE PLATES ON THE BOOT CAN BE SWAPPED FOR A FRONT OR REAR PLATE IF NECESSARY! PLEASE CONTACT THE STORE IF YOU WISH TO MAKE THE CHANGE BEFORE PURCHASING!
