Although I have somewhat wide feet, I usually have no problem with sports shoes and they tend to fit me just fine. These did feel more narrow than usual and just walking around the house made my feet hurt. It also felt like the heel was slipping down with each step (I have a narrow heel). The sole did feel thick enough to run on trails, but the insole was a little too hard and stuff for my liking. Overall, it appears to be a decent shoe but didn't work out for my feet.
