Byerly Wakeboards Byerly Boa Wakeboard Boots 2010: From the creator of the original forward lean design comes the latest innovation in boot flex and control. The new Byerly Wakeboards Byerly Boa Wakeboard Boots utilizes BOA technology to control the amount of forward lean you want in your boot. This fully adjust on the fly system allows a rider to go from 0 degrees to 20 degrees of forward lean in the cuff of the boot, while never affecting forward flex. This feature combined with the dual Quick Cinch lace system for customizable tightness and the new Low Pro plate which put the rider closer to the deck of the board, makes the Byerly BOA the most technical boot in the line.
