Leatt GPX 5.5 FlexLock boots come to market following a three-year project development process using their pro athletes for testing and input. Leatt is committed to protection, but developed the GPX 5.5 with looks as an important caveat. It uses a FlexLock system that makes for adjustable boot flex, lockout of ankle movement, force reduction to ankle (up to 37 percent) and knee-force reduction (up to 35 percent). It has a SlideLock Velcro top closure, 3D-shaped impact foam over the ankles, a heel-grip ankle design, and the toe box is low-profile and shifter-friendly. The Leatt boots’ sole has a DualZone hardness and has an extended footpeg zone to accommodate varying riding styles with a steel shank for additional support. It uses a gripper inside for rider feel, the buckles are forged with an over-locking function, and the inner liner is breathable mesh with anti-slip reinforcement for zero heel lift.
