Not bad, not great about average.
Size: 10, Color: Navy Faux Leather
Honestly you get what you pay for with these I lucked out because of the price point. They look ok, they're not horrible, they're not fantastic, but they're doable. They hold up pretty well I've worn them to work and I walk a lot at my job so so far so good.
