Customer Reviews

Comments: Update to previous review. I have used them for about 50 miles on the road and they're spectacular. Comfortable, nice spring, soft landing per each step, etc. can't comment on durability much yet as I've used them on the streets for running for two weeks and casual walking for a month. Small pebbles will get caught on the bottom in the drainage ports but that won't effect your run.

Comments: This is an extremely comfortable shoe. I have not used it for running (I know that's what most people come here for; for the record, I race with Adidas Hagios) but for casual everyday wear, this is awesome. I was looking for something with a minimalist feel with some support, a cool design, and solid structure that in an instant, I could use as a running shoe if I wanted to. This definitely fits the bill!
