This is one of the most comfortable running shoes I've ever had. And I run at least 10 miles every day. This may be a factor in how quickly I wore out the hole in the sole of these shoes - they only lasted 4 months before the ball burst on the right shoe. For the price, I wish the outsole was made of a more durable material. However, if you don't run as much as I do, these are fantastic shoes. I especially like how the sole wraps around my toes - very nice when I trip over my toes a lot!
