Reviewing shoes used to be straightforward. Lightweight shoes were meant for racing, heavily cushioned shoes were meant for efficient runners who racked up lots of miles, and stability shoes—with a section of dense rubber under the arch, a.k.a. a medial post—were meant for people whose feet collapse inward.

And guess what. Hardly anyone bought ’em. Thank goodness that those days have finally come to an end.

Kicks designed specifically for the female foot, including The North Face Single Track Hayasa, best for mixed road and trail runs; the Salomon XR Mission, best for long trail runs in rough terrain; the New Balance 890V2, best for a cushy on up-tempo runs; and the Pearl Izumi Kissaki, best for high-mileage marathon training and racing.
