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.

Nice men’s shoes

Size: 9.5, Color: Khaki Brown

I bought these shoes while costuming a show at the local community theater. The man who wore them said that they were comfortable and easy to get on. They came exactly as described and pictured.
