Leatt 5.5 FlexLock Enduro Boot - Graphene

ULTIMATE COMFORT AND FORCE REDUCTION PROTECTION 

The 5.5 FlexLock Enduro boot offers exceptional rider protection and comfort, even on all-day rides. The FlexLock system reduces forces to your ankles and knees by allowing your ankles to flex sidewards slightly before locking out. The SlideLock auto-locking one-way sliding closure system makes it easy to close the boot with gloves on and provides a great seal. The flat and grippy interior of the boot enhances bike control and feel, and the Enduro pattern sole provides excellent grip when pushing the bike. 3D-shaped impact foam over the ankles delivers added protection. A breathable mesh liner and anti-slip reinforcement prevent heel lift, maintaining comfort and stability throughout the ride.

Set the FlexLock flex adjustment before your first ride and re-check it after a few outings — the lower boot flex is adjustable to suit your preference and riding style.
To close, slide each buckle down into the SlideLock closure; it locks one way automatically, so you can do it with gloves on. Release using the Over-lock lever on the forged aluminium buckle.
Allow a short break-in period of a few rides for the boot to mould to your foot and the sole to soften; don't start with an all-day ride in brand-new boots.
Knock off loose mud and grit after every ride, then wash the outer with lukewarm water, mild soap and a soft brush. Avoid solvents, petrol, brake cleaner and harsh degreasers, which can damage the outer materials and bonding.
Rinse the sole tread and the buckle mechanisms after muddy or sandy rides — grit trapped in the SlideLock track is the main cause of stiff or unreliable closure.
Dry naturally at room temperature with the liner exposed and the buckles open. Never dry near a heater, fire, exhaust or in direct sun, as heat can distort the shell and shrink the liner.
Pull out insoles and air the boots fully between rides to keep the breathable mesh liner fresh and limit odour.
Before each ride, check the buckles, straps and stainless steel bases for cracks, bending or missing hardware, and inspect the sole for excessive wear or separation. Replace worn buckles and straps rather than riding with a compromised closure.
Store upright in a cool, dry, ventilated space out of direct sunlight, with the buckles lightly closed so the boot holds its shape.
Retire the boots after any crash that causes visible damage to the shell, ankle structure or FlexLock hardware — the protective performance can no longer be relied on.
