Product Review

The Altra impulse flash is a perfect blend of flashy reflectivity and lightweight dynamic support. Like the original impulse, the impulse flash features inner flexâ„¢ and stabilipodâ„¢ 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 footshapeâ„¢ toe box keep your feet comfortable whether you are running, working out at the gym or walking the dog. The fully cushioned zero dropâ„¢ platform encourages a more natural, low-impact foot strike and features a lightweight, responsive a-boundâ„¢/eva blend midsole.
