The NSI Ratchet Kite Straps are built with the same consistent high quality materials as the original wide kite footstrap. The strap design has an integrated ladder strap and ratchet buckle with upgraded stainless steel components. This accommodates a huge range of adjustment that completely cements your feet to the board with comfort and no hot spots. Easy on the water adjustment and you can change your footwear and still use the same straps. Great in schools and for multiple users of a board. Four stainless steel washers included.
