Review on Black Mizuno Prophecy Running Shoes by Oscar Chambers

Hello, I have been using Mizuno Wave running shoes for a few years now. I have decided to buy Prophecy running shoes from your store. However, after using these shoes, I got cleft shins. I went back to my old running shoes for a few days and the shin splints were gone. Prophecy shoes hurt me. I want to replace this shoe with a newer treadmill model. The return window is 30 days and I kind of missed the return window. I seem stuck with this shoe now as I don't see a way to contact the seller for a refund/replacement? I called Mizuno directly but they couldn't do anything and told me to contact Revine.
