The Mizuno Wave Lightning Z4 is super light and very agile on the floor. Compared to the Z3, the Z4 has a completely renewed upper with an even sportier design and better breathing qualities. This indoor shoe weighs only 225 grams. The seamless superstructure ensures a comfortable fit and the Mizuno Parallel Wave plate and the EVA material enable the finest damping after every jump or step. The midsole material, which consists of the very best PoWCe, reduces the weight of the sole without compromising on the damping. A lighter sole with the same damping provides even more performance in the room. By adding D-Flex grooves in the sole of the Mizuno Wave Lightning Z4, front, back and lateral movements can be made quickly and easily. This makes an acceleration even simpler and more natural. The SR Touch insert provides even more cushioning at the forefoot, so that the toes receive fewer shocks. Immediately convert these shocks into a good forward movement or jump is provided by the new Kick-Sensor technology.
