3 year ownership. Worst running shoes I've ever had. If the ground is wet, you can walk on ice regardless of the nature of the ground. The shoe is designed with the toe and heel sticking out enough to interfere with your natural ability to move without paying attention to where your feet are going, leaving you constantly kicking things and tripping over everything. Because of this issue, I had to cut off two 1/2 inch pieces of rubber from the tread that were sticking out from behind the toe. Don't waste your money on these terrible design shoes. The ONLY good thing about them is that they can be worn like slippers.
