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.

Look great for dress up up casual

Size: 13, Color: Black Leather/Optic White

I wear them every day for work. They are comfortable and light. I will say I was frustrated with the crease in the top that started the first time I wore them but other than that they are a great pair of shoes.
