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

Great pair of shoes
Size: 10, Color: Burgundy
I was a bit concerned that these shoes would be a bit large because I normally wear a size 9 1/2 and these are a size 10. But they fit perfectly. They are very light and comfortable. 👍
