The Leatt 5.5 FlexLock boot, was a 3-year project with long term development and testing using our Pro athletes from all over the world!
The 5.5 boot is a real head turner when it comes to looks and style, but the design brief was comfort and protection also, and we nailed it first time.
As you slide your foot inside our boot you instantly feel the plush interior and quality of the materials used, it’s like putting your feet inside your favourite shoes or slippers!
Our adjustable FlexLock system reduces forces to the ankle by up to 37% and the knee by up to 35% by Locking out the ankle movement when over flexed, giving you that feeling of security.
With great feel of the frame, gear lever and rear brake, these boots instantly feel so good.
