Carried over from the Kevin Durant Basketball Shoes collar are molded notches in the heel, which provide just enough resistance to lock your heel securely into place. My heel felt securely locked down both laterally and vertically, which gave me confidence in the ankle support department.While the upper has some similarities to the Nike Zoom KD II, it also features some of the biggest differences – and in my opinion, improvements. The Kevin Durant Basketball Shoes strap offered some midfoot security, but wasn’t entirely necessary.
