Amazing dress shoes! 👞
Size: 12 Wide, Color: Classic Brown, Size: 12 Wide, Color: Classic Brown
These shoes are a 10/10! Our groomsmen loved them, very comfortable, and the color gradient is even better than pictured! They matched our groomsmen’s outfits perfectly as we got their entire outfit from Amazon. Water resistant and easy to wipe clean. The material is like a tough leather so it keeps its shape and has a professional and sleek appearance. Great value for your money! Would purchase again.

Good value and very clean stylish look.
Size: 9.5, Color: Classic Dark Brown
I REALLY like these shoes, for the price they are very comfortable and the materials seem pretty solid. I'm not an expert on quality stitching but these seem to be pretty good. I got them for my wedding and they looked fantastic. I now wear them to all sorts of fancy events and they are holding strong!
