I was introduced to Mizunos in Dick's Sporting goods by the sales associate over 3 years ago and I have yet to be let down with this shoe. I was a heavy distance runner for some time and these shoes hold up almost 9 months with regular use (300 miles) with 235 lbs on top of them. I am so happy with the Wave Rider 14 I bought a new pair on here to replace the ones I have been wearing for over a year.
