The Raptor WCR 140S is designed directly off of the WCR racing line, but in a slightly wider last. This boot has been upgraded with a deeper heel pocket and a longer toe box, resulting in an even better fit and optimal power transmission down. The boot has adjustable flex and comes with Head's popular WCR Pro liner with Liquid fit. With Liquid fit, the liner can be moulded to give the perfect fit for your foot. Four micro-adjustable low-profile Spineflex buckles deliver an optimum athletic fit and responsive feel.
