I have 3 pairs of these shoes. They are super comfy. The price is amazing for a shoe so well built. They are light weight look really nice on. Buy them, well worth the money.

Avoid These Shoes
Size: 10, Color: Grey
The pair I received (gray) was not represented well in their photos. Mine had a lime green logo which looks silly. They also bunch up very badly when you pull the laces which looks ridiculous. Cheap feeling and look bad when tied. Sending back
