Updates to Mizuno runningshoes are done according to a strict pattern. Every year the upper will be changed and every two-year the midsole and outsole will be redesigned. This Summer we will see the release of the Mizuno’s lightweight performance trainer, the Wave Sayonara 2. And sticking to the pattern, the shoe has a slightly redesigned upper in the form of new graphics and a small amount of material has been added around the midfoot, giving the shoe a slightly more accessible fit. Also, the few seams in the interior of the shoe have been completely removed for reduced hotspots and a more socklike fit.
The Mizuno Wave Sayonara 2 will be available July 2014.
