Usually when I buy brand new running shoes, it takes a few runs for them to start breaking in. With these, I never had that problem. They felt good from the start. That helps me out since I run more like a penguin than a gazelle.
I honestly never thought about the shoes the entire time. Even right now when I think back about it nothing comes to mind. So I guess that means they did their job perfectly.
The shoes had a great cushion system that I found to be very helpful in long distances. I want to start training for marathons and this is going to be a huge issue.
