2027 Leatt Moto 5.5 Flexlock Evo Boots in White

The Leatt Moto 5.5 Flexlock Evo combines a protective motocross boot construction with the flexibility needed to work comfortably on the bike. TPU protection covers the shin, ankle, heel and foot, while the revised collar, front and rear bellows and updated closure allow the boot to move with the rider.

The adjustable FlexLock system is one of the key features. It can be set to limit excessive ankle movement, with Leatt quoting reductions in ankle forces of up to 37% and knee forces of up to 35% when the ankle reaches over-flexion. The rear torsion blade works alongside 3DF impact foam over the ankles to control front-to-rear over-flexion.

On the bike, the low-profile toe box gives more clearance around the gear lever, while the 3D bottom shell and extended footpeg riding zone retain useful feel through the pegs. The heel grip ankle design and anti-slip reinforcement add stability around the foot.

Boot Construction and Closure

The upper uses TPU construction with a reinforced TPU heel counter, while four forged aluminium buckles use an Over-lock system with stainless-steel bases. At the top of the boot, the SlideLock Velcro pull-tab provides an auto-locking, one-way sliding closure.

The collar has been updated with a new construction and elastic fabric, and the ankle volumes have also been revised. Inside, the two-piece padded and water-resistant lining provides additional comfort. A steel-shank reinforced sole uses a DualZone hardness design and is CE certified.
