Great dressy sneaker to wear with business casual or jeans
Size: 11, Color: British Tan/Ivry
I got these for my husband to wear with jeans or business casual dress pants. They look sharp and professional and dress up jeans if you're going out. He says they fit comfortably and he can walk on them all day without his feet hurting. They are beautiful genuine leather so they don't get stinky. I got my husband's normal size and they fit to size.

Comfortable
Size: 9, Color: Black/Ivory
Most comfortable and roomy shoes I ever wore. Great for insoles. Looks nice too. The base of the shoe is a bit too thick but it’s fine.
