This shoe is unisex. Sizes are men's. A crossover shoe with everyday appeal, the new Transport X is geared to propel runners through their daily life. Sleek enough for everyday wear and speedy enough to pick up the pace, this versatile trainer features a propulsive carbon fiber plate, responsive midsole foam, and smooth-riding rocker for effortless heel-to-toe transitions. Finished with 360-degrees of reflectivity for nighttime visibility, there’s no telling where the new Transport X will take you.
