A soft sock-like construction made of a lightweight stretch-knit upper offers breathable comfort while the interior padded heel counter secures the back heel. Slide into Qool, with a pull of the tab and tighten for a glove-like fit with the added laces. All set on our exclusive Q-flow outsole, which ensures flexible movement with added breathability.
