BEST FOR: Ultraminimalist midfooters.
THE TEST: Frankly, most of the slipperlike shoes out there are pretty darn similar. What made the PureDrift stand out is that it’s convertible: with the removable insole in, it’s a four-millimeter-drop shoe; take it out and you’ve got a zero-drop shoe. Testers liked the PureDrift best in four-millimeter mode, as removing the sole only increases the shoe’s already high-volume fit. (The upper has a tendency to fold and buckle on narrow feet.) We did appreciate the eight-millimeter midsole, which helps to slightly soften the slap
THE VERDICT: A smooth take on a barefoot slipper, with an innovative twist. 5.6 oz; zero or 4 mm drop.
