This revolutionary boots has taken the comfort and performance to a new level. Gaerne found that by creating the rear entry design, adding the upper pivot protection system as well as the gel ankle, that we have really captured a great fit. On the exterior of the boot, you will notice some new features as well. Starting with the rubber "Grip Guard", this feature will allow you to feel like a part of the bike when riding. Next you will see the aluminum buckles, the toe slider as well as the rear hell cap. These features not only make the boot look good, but will help extend the life of the product. Last but not least is the all new anti-vibration Gaerne sole for just the right feel on the pegs. Features: New adjustable and replaceable aluminum buckle system. Gaerne razorback pivot system. New toe slider. Rear heel cup. Rear entry design. The exclusive Gaerne floating system surrounds the ankle while at the same time flows with your natural movement to ensure a great fit. The length of the buckle strap can be changed by manually adjusting the teeth of the strap to the desired position, rather than using the buckle as a ratchet like the Marathons.
