This is my second Wave Inspire from Mizuno for men. After version 14 I switched to version 15 and so far (about 80 km) I am very happy with it. As with the predecessor, I am very impressed with the cushioning of the sole. It is very comfortable and has a "springy" feel that reduces stress on the joints. I like the outsole characteristics of the Mizuno much more than the Brooks Adrenaline GTS (version 18), my other running shoes, which feel flat and hard and wear out very quickly. So thumbs up! They really put some good materials and engineering into these shoes.
