They have HOLES in the bottom. Actual holes. So if you run over soft dirt, mud, gravel, the dirt/mud/gravel gets stuck in the stupid holes! And then you track it in the house. I had a tiny pebble stuck in one of the holes and it scratched the wood floor in my house. I ran thru mud the other day and now it's all dried up in the holes. I'm going to have to blast them with the hose to get the dried mud out otherwise I'll be tracking it everywhere I go. Seriously flawed design.

It's a nice shoe but for me, it's uncomfortable. I don't have a high arch so the arch support is too much for me. If it weren't for that, it'd be fine.

Just like the many other Nike shoes I have worn, this pair lived up to all of my high expectations. I often experience foot pain as I exercise and Nike seems to be the only brand that fits my needs. As a sprinter, I do everything from stair laps and box jumps in the gym to sprints and jogging on the track. This pair still feels good on different surfaces. The Nike Renew Rival remains comfortable and still looks hot!
