Extremely high quality

Ordered these shoes for my husband. They fit your correct size and are extremely high quality. They look amazing and my husband says they’re comfortable.

Very comfy and a really nice shoe—one flaw, but I still recommend it.
Size: 11.5, Color: Black Grainy
These shoes are nice, comfortable, with a sleek, leather-like insole that allows your foot to move well. The only thing they could have done better is extend the sole slightly farther at the tip. As it is, the lower front part of the shoe tends to scrape against the pavement, causing scuffs. It’s nothing that can’t be managed with shoe cream, but over time, the abrasion may cause more serious damage. That said, for the price, this is a nice shoe and should easily last at least a year.

Marc Joseph's Shoe 👞
Size: 8, Color: Tan Napa
Marc Joseph's Shoe 👞: I ordered a size 8 for my husband. He wears socks with his shoes. It’s a little tight slipping on. Other than that, the shoe is very comfortable. My husband grabs them all the time because they are so comfortable.
