I run about 4-6 miles on a daily basis. I have alternated between the Mizuno Wave and the Asics Gel Kayano. Due to early inner sock heel wear on the Asics, I have found the Mizuno is my shoe of choice. I recently decided to try this shoe and it is one of the most comfortable running shoes I have ever had. The shoe has no abnormal inner sock wear when I run and fits well. It is expensive but I have no regrets.
