Snazzy Looking and Cost-Effective Dress Shoes
Size: 9.5, Color: Black
The shoes fit great and look very nice. They keep their shine and comfortable. I would say there are two drawbacks. 1. When you put them on, the tongue pushes up far and you have to pull it back. 2. There is little to no arch support and would recommend insoles if you have any foot condition. I haven’t had these through a snowy and salty winter.
