Perfect fit, perfect comfort and perfect style.
Size: 9.5, Color: All Black
Very stylish and extremely comfortable. It feels like you're walking on a cloud! It is made of great and strudy material and the quality is excellent. My size also fit me perfectly. I would definitely buy it again.

Insoles suggested.
Size: 12, Color: All Black
Nice, business-style, soft, shiny, leather-like material, extremely light and well cushioned all around. But, there is little or no arch support, which make these shoes NOT for all day wear, unless an insole is inserted. The slip resistance is not great, but acceptable. Still, very good for the price.

Great shoes!!
Size: 8.5, Color: All Black
Really comfortable I feel like I’m walk on a cloud.
In terms of the shoe quality, I work in these for retail, they do crease quickly within 2-3 days. They fit true to size.
