Comfortable

Super comfy and stylish, I’ve never worn these styles of loafers however I’m glad I purchased these.
I’ve purchased another pair in a different color.

Outstanding quality
Size: 11, Color: Black Faux Leather, Size: 11, Color: Black Faux Leather
The loafers are very comfortable with the puffy insole, very nice quality, and overall a very good shoe. I suggest a half a size up because they are kinda narrow.

nice loafer
Size: 10, Color: Brown Faux Suede
comfortable and nice-looking loafer. i wear 10.5 and ordered 10 and they fit fine. haven't worn them much yet so i can't say how they'll hold up but seem pretty nice for the price.

Great Bang for Buck! SIZE DOWN!
Size: 11, Color: Tan Faux Leather
The Quality of these shoes are great! They feel good, are a deep brown color, the stitching is good, all in all great shoes. They are comfortable to walk around in making them a versatile choice for any occasion. My only issue was sizing. As everybody says these shoes run big, I am usually a 10.5/11. I went with the 11s and they are slipping off my heels. Size Down!
