N.A.S.T.Y. SpeedEntry has never been more convenient without sacrificing the superior performance, comfort and power transmission that our bindings are famous for. With our revolutionary New Active Strap Technology (N.A.S.T.Y.), the strap automatically lifts up when you open the reclining hiback and actively tightens again when you close the hiback. N.A.S.T.Y. reduces friction and creates more room so that getting in and out of your bindings is faster and easier than ever. * Modback Hibacks:These modular hibacks separate the lower and upper zones, using a strong and reliable Aluminum alloy heelcup, which on the NX2-Series also automatically triggers N.A.S.T.Y. The upper zone uses independently adjustable SupportPanels with model-specific shapes and flexes to deliver fine-tuned performance. * Bankbeds:BankBeds are full-length EVA footbed with 2.5 degree canting and adjustable toe-ramp optimized fit, support and energy transfer. * Fusion Powerstrap:3-D shaped, the Fusion PowerStrap fuses the ankle and toe zones over the midfoot and is padded for a super comfortable form-fit to your boot. Choose between either the symmetrical I-FUSION strap for great all around support and freestyle feel or the asymmetrical A-FUSION strap for extra lateral support and responsiveness. * Rockered Baseplates:All of Flow"s baseplates are uniquely engineered to transmit energy directly to the board without a loss of efficiency or natural board feel. The minimized contact area with the board channels your power where it needs to go, while the rocker corners of the baseplate allow any type of board to maintain optimal flex.
