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.

Absolutely great
Size: 10, Color: Navy Blazer/British Tan/Ivory
Bought these for an Italy trip to dress up in a dressy casual style. Walked 20k+ steps daily in these for 13 days straight and my feet were comfortable all day long. Highly recommended.
