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!

Size Down

Size: 7, Color: Tan Faux Leather

Out of box review: Love it, comfortable and looks great, has bit of a thicker sole than expected. Definitely size DOWN (One size down fit perfectly)

Overall very good

Size: 9, Color: Black Faux Leather

I liked these loafers very much. The sizing was true, and on point. Fit was comfortable, and the sole’s height wasn’t too exaggerated. Overall very satisfied given the price, however I do wish they looked a bit more luxe,
