The new Radar Hybrid Rear Toe (HRT) blends the conveninece of a rear toe strap with the control and leverage of a rear boot. Thether 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 heel cup 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. The HRT is built on a standard size Vector Chasis. One size fits most.
