The Nike ACG Mountain Fly Low SE ‘Ironstone’ updates the outdoor sneaker with a low-profile silhouette. Beige ripstop textile is utilized on a bootie-style upper lined in padded mesh for a comfortable fit. Reflective threads are woven into the wraparound rope laces, which feed through webbing straps for a feeling of lockdown. The lightweight build rides on a Nike React midsole, supported by a full-length shank plate and a lugged rubber outsole.
