The Arch of Progress
Your new trail shoes sure feel nice and squishy, don’t they? That’s the ethylene vinyl acetate working—the foamy layer under the manufacturer-supplied footbeds. But while EVA delivers decent shock absorption, it offers not a lick of motion control for overpronators—those of us who roll our feet inward while running. Neither does that bare-bones footbed. Avoid rolled ankles, shinsplints, and blisters by dropping extra coin on an aftermarket insert, like Shock Doctor’s new UltraRunning ($30; www.shockdoc.com). A rigid cup locks your heel in place on impact, a plastic frame combats overpronation by lifting your arch, and a raised area over the midsole improves stability on off-kilter landings. Other good options are Superfeet’s thickly cushioned Performance ($35; www.superfeet.com) and Montrail’s new Enduro-Soles ($35; www.montrail.com) plastic footbeds, which bake in your oven for a heat-molded custom fit.
