Brooks’ top tier sprint spike is updated with their latest aesthetic spin and technological and material improvements. The upper receives a new non-stretch synthetic textile, with welded overlays and a snug fit securing the foot over the plate.
As in the previous versions of the shoe, a thin innersole acts as a midsole for the shoe, resulting in a light, quick (remember the name), spike for the fastest running events. The outer sole is a full length Pebax nylon spike plate which features 7 reconfigured spike receptacles. The adjustments to the forefoot angle, plate design and flex, spike placement, and fit have resulted in a greatly improved version of the QW-K, and an excellent choice for sprinting performance.
