These shoes are fantastic. This is my second pair of the shoes and I just ran the Marine Corp Marathon in them. I finished and my feet felt great! 5 stars

After visiting two separate running stores I decided to purchase these. I had several great runs in them until the fabric at the back of the heel (inside the shoe) began to stretch out of shape. The stretching caused folds which then led to blisters. When I contacted Mizuno for help, they insisted that I send the shoes to them for inspection. Many emails later, I still do not feel satisfied with the customer service, and I think I might have to just buy another pair of shoes. They were great while they lasted, but that wasn't long... 3 stars

Thanks so much for the Mizunos. They were exactly what I was looking for. Appreciate the fast shipping too! 5 stars
