HRT The Hybrid Rear Toe (HRT) blends the convenience of a rear toe strap with the control and leverage of a rear boot. Whether you kick in or lace up, the complete closure ensures your foot stays put, allowing you to create leverage against the back of the boot. The high tongue and low heelcup allow you to kick your foot in after a drag or dock start. It’s the best of both options, regardless of your previous rear boot. Electric Coral Feather Frame available in small.
