Gett'em
Size: 10.5, Color: Black
These shoes look and wears very nice. I also have them in Brown. They work well with slacks, khaki and jeans..it's definitely a all purpose shoe. I feel that the fit is true to size..unless you have wide feet.

Great for skinny feet
Size: 8.5, Color: Black
Son loves these for his dress shoes. He prefers high tops since he has skinny ankles - these have an elastic type top that helps keep your foot in if you have skinny feet. He says they are very comfy and has worn them all day for school events.

great dress shoes
Size: 10, Color: Black
I needed to rent a tux for a wedding but did not like the dress shoes available from the tux rental store. The shoes they offered looked really nice but were not very comfortable. These shoes look just as nice and are much more comfortable. Of course I wanted to look good but I also wanted to be comfortable; these shoes checked all the boxes.

Got these for prom and was incredibly pleased with my purchase. These shoes looked so damn good with my son's tux and were comfortable for the entire evening.
