This is my first time wearing a Bruno Marc MaxFlex Dress Sneakers Oxfords Casual Wingtip Brogue Shoes. I was quite impressed how the shoes arrived and how they had a protection bag over each shoe. Very impressed by that, The shoes are very comfortable , lightweight squishy and affordable and very stylish. I recommend them.

Comfortable and complimentary
Size: 11, Color: Brown
The shoes are very comfortable and easily broke in after two wears. I get several compliments on them daily, and others have purchased them after seeing mine. I also have the black pair, but the brown ones are my favorite. Sizing is true to size, an excellent value for your money, and they are lightweight and breathable. The soles are thick, which makes them extremely comfortable.

Nice but not ideal sizing.
These look nice. They do not have a traditional tongue, replacing it with some sort of elastic lining. They do fit larger than expected. I purchased wide since normally need that and it creates a bump just below the laces. Also, after size 11 there are only whole size increases. I feel an 11.5 regular would have fit better. They are pretty comfortable with a cushiony insole and thick sole.

Comfy and non slip! Amazing!
Size: 9.5, Color: All Black
I work 12hrs sometimes on my feet. These shoes are amazing !!! Broke them in on a 10hr shift and they feel like walking on pillows. My feet were comfy and not throbbing. I felt the difference in the non slip in the kitchen and I’ll say it outright……. Worth the $40! I got the brown coming and I’m assuming they’ll be just as comfortable. Bruno Marc’s are great!
