Mizuno's top-tier, max-cushioned running shoe, the Wave Sky 4, is designed for the best running feel Mizuno can give. 
Designed with a 'Xpop' and 'Enerzy' cushioned midsole, the Wave Sky 4 is designed for maximum cushion and maximum response - to give you all the soft sponge you could ever want but with more bounce than any comparable shoe. 
As an added benefit, the footshape and deep heel collar combined with a removable sockliner and neutral platform, make this a favourite for podiatrists and physios looking for a stable platform for orthotics.
