Setup, Compatibility & Care
To ensure the best experience, confirm your size before your first run; the internal gusseted structure creates a snug fit, so you may prefer a slightly thinner sock. When lacing up, ensure the tongue is centered to maximize the effectiveness of the internal support system. To care for your Mach 7s, avoid washing them in a machine as this can degrade the foam and adhesive. Instead, wipe the upper with a damp cloth and mild soap if they become muddy. Always air dry them away from direct heat sources, such as radiators or heaters, to prevent the midsole foam from warping or hardening.
