The new TCX boot line, formerly Oxtar, sets the standard for protection in high-end boots by
offering the latest in ankle support technology, and is preferred by riders such
as Kevin Windham, Nick Wey, Blake and Tyler Wharton, Justin Barcia, Cernics Kawasaki and many of todays top privateer and amateur racers. The TCX Pro 2, and Combat all offers the patented Torsion Control System (TCS) and Foward Control System (FCS) which allows controlled lateral and front to back bending movement of the ankle through 4 flexure points on the sides of the boots, and 2 flexure points on the heel. Simply put, the TCS helps prevent hyperextension of the ankle by providing stopping points without restricting movement. If you value your ankles and feet, and you want the best to help you go faster than your competition, then you should be wearing TCX boots.
