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.

Fit of shoe
Size: 9.5, Color: Brown
The shoes seems to run a bit narrow and tighter than the stated size. I plan to reorder the wide in the same size. They look great but I needed an easy to slip on shoe for my husband.
