The Altra impulse flash is a perfect blend of flashy reflectivity and lightweight dynamic support. Like the original impulse, the impulse flash features inner flex and stabilipod technologies to give you flexible support where you need it, but the upper is made of an entirely new, fully reflective material for style and safety in low-light situations. The friction-free, lightweight upper and footshape toe box keep your feet comfortable whether you are running, working out at the gym or walking the dog. The fully cushioned zero drop platform encourages a more natural, low-impact foot strike and features a lightweight, responsive a-bound/eva blend midsole.
