You may think that it's a crazy for a shoe company to construct a men's running shoe without a midsole. But after seven years of intense research, that's exactly what Mizuno did with their new Wave Prophecy ($200). Instead of the traditional foam layer, The Prophecy utilizes two stacked plates that act like a suspension system to provide amazing cushioning and shock absorption. Along with its lightweight design, this running shoe is also built with a forward propelling system that helps you log more miles.
