Customer Reviews

Comments: The foot pad came off after a few runs. They're really light and thin which is great to go faster, but because of that, they tear really easy. I only had mine for a couple of months. They did not last on the road, but they're good for the track. AVOID ROCKS WITH THESE SHOES. THEY'RE THIN AND WILL TEAR

Comments: Great shoes for running fast (set a 10k PR in them). Not a lot of cushion. I've put 15 miles on them and they're holding up fine.

Comments: Like the shoe but the contact patch came off the shoe, within 3 runs. Now the shoe has no grip to the road.
