The Mizuno Wave Rider is closing in on 30 iterations and its success as a daily neutral training shoe has long-been due to its longevity and smoothness. The Wave Rider is one of the most durable running shoes that you can buy because you can beat it to death and it will still deliver a quality run.
Recently, Mizuno has improved on the Wave Rider's comfort and stiffness with a more porous upper and a full-length Enerzy Foam, which is softer and more responsive that previous Wave Rider midsoles. As a result, the Wave Rider (while slightly more on the expensive side for a trainer) is one of the best daily running shoes you can buy.
