The ProForce Ultra Lightning Kick is made with a new contoured instep design, which allows for better air flow and more padding. A 1/2" thick vinyl covered foam offers protection for sparring over the entire foot and ankle. Cutouts around achilles and instep provide for better dexterity and mobility, and open areas at the heel, ball of foot, and toes allow for better gripping on floors. The bottom has two reinforced vinyl straps to keep the boots secure, and an elastic strap fastens the boot with a hook and loop closure.Women order 1 size smaller.
