Developed for the high-mileage runner requiring the highest level of cushioning and comfort, the new Wave Horizon 5 also provides a more natural stability system cleverly worked through it's cushioning technologies. It contains a full length XPOP foam, which makes you feel like you are floating whilst running. The structure of the XPOP is also designed to slow down pronation, giving the shoe a great combination of cushioning and support. This combines with the all new Enerzy midsole, which makes the shoe even more cushioned and bouncy, providing you with the most luxurious but stable run. Full length XPOP provides a completely new type of midsole compound that delivers cushioning, rebound and stability at the highest level. The great harmony of the super soft cushioning with high energy return makes you feel as if you are floating along on your run from heel to toe.
