5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Excellent value

Size: 13, Color: Brown

These boat shoes are great, they fit a 13W comfortably, for the the price my expectations were not high, but I was wrong, they look good and the soles are real rubber they fit well, I would definitely recommend these, very comfortable.

Good value and comfortable

Size: 8, Color: Khaki Brown

I'm going to give these shoes a 5 star. They look good, fit well and are very comfortable. They are not leather, but they look and feel more like leather than most low-priced real leather shoes. I bought them to wear around the house and in the yard and they are perfect for that. I am going to swap the weird looking partial laces for a good pair of leather laces. Good value received for money spent.

Way, way, way too narrow

Size: 11, Color: Brown

Absurdly, uselessly narrow. I can't get my toes past the opening, although the length appears to be close to correct. A 8 year old might be able to get into my size 11s and flop around in them, but not a grown up.
