Versatile and well priced
Size: 11, Color: Black
Great for the price. Look good for kicking it around town or for a business casual work place. They fit great, they're comfortable, the black is deep, and the price is right.

Becareful of the shoe size
Size: 8, Color: Black
the size was not what i expected, most shoes i wear have always been a size 8, but this one was a bit tight. I asked a question on the page if the size is based on UK or US since there's a 1 size difference. but it said it was US standard reference. perhaps buying a size 9 would fix this issue for me. The quality of the shoes however is very great, compared to the basic shoe affordable brands you get this one has better quality, they're light and great whether you're stationary or actively jogging or walking. just the size was lacking in fit.

Not recommended
Size: 9.5, Color: Navy
Not comfortable and hurt my ankle. Makes weird leather sounds while walking. Looks good but go for a different shoe if you are looking for comfort.
