Leatt 5.5 FlexLock Boots

The Moto 5.5 FlexLock Boot is built for riders who demand pro-level performance, exceptional comfort, and serious protection. With no break-in required, it’s track-ready straight out of the box. The FlexLock system helps reduce forces to your ankles and knees by allowing controlled lateral flex before locking out—helping you ride harder, longer. The SlideLock closure makes securing the boot easy, even with gloves on, and ensures a great top seal. A low-profile toe box makes shifting intuitive, while the flat, grippy interior enhances bike feel and control. Inside, a mesh liner with anti-slip reinforcement keeps your heel planted, while 3D-shaped impact foam adds extra ankle protection. CE certified, the 5.5 FlexLock delivers uncompromising fit, feel, and function.
