Great gift for any guy!
Color: Black Leather/Black, Size: 12
These are one of 2 pairs of work shoes my husband will wear, the other one is the same shoe in brown. He says they’re the comfiest pair of dress shoes he’s ever had and the quality and ease of cleaning is incredible. They’ve lasted him years now so I’d say they’re well worth the money.

Great shoes
Size: 10 Wide, Color: Brown, Size: 10 Wide, Color: Brown
This shoe is incredibly comfortable and durable. I work in custodial work as management. However, sometimes I have to help my team when we are low manned. Just recently I had to help my team auto scrub a restroom. My shoes felt lightweight and were completely easy to clean. I was worried I would be slipping on sudsy water. To my surprise, these shoes gripped on to the floor nicely. I love the versatility of having a working shoe with the great style Bruno Marc provides. The shoe is breathable and true to size. I ordered the black pair as well and have had them for about 3 months. Highly recommend these amazing shoes.

Great quality.
Size: 8.5, Color: Brown
Bought these shoes at the last minute for my husband to wear to an event. They arrived overnight and did not disappoint. They are true to size, high quality, lightweight, and they look great on. Can be worn with jeans to a casual event or with slacks to a more formal event . He loves them and said they are extremely comfortable.
