From a Long Time Hard Sole Dress Shoe Wearer, These are a Must Have!
Size: 12, Color: Blue
I have been wearing hard sole dress shoes for decades and with the full COVID shift to dressing super casual in a professional work environment, I was in the market for some more casual let dressy shoes that were a heck of a lot more comfortable and flexible than my hard soles so I thought I would give this brand and style a try. Oh man, I'm in love. These give you that dressier look yet you can totally dress them down with jeans or cordouroys, so versatile. As I did with my hard soles, I inserted one of my Nike Air in soles and man, these are so comfortable I bought navy and brown! I usually wear these with thin dress socks and they go perfectly with any type of suit set, a no brainer purchase here. I'm a 12 and bought a 12, perfect fit, not to skinny, not to wide, just right. Bottom sole grip is impressive, never felt unstable, solid rubber sole here. I decided to lace them up so there are not tying and the tongue does slip down sometimes so with this feature, best to use a metal shoe horn, then it's super easy to slide them on, they seem to take a beating and remain clean too, I've definitely scuffed them up against many things and still no damage, it's crazy, must have a great finish. NOTE TO Note to MANUFACTURER/SELLER - You need to make a version in GRAY in this specific style and I will buy them instantly, and I assure you they will be incredibly popular! Really not sure why there isn't more colors in these like gray, shades of gray, maybe red, lighter blue and maybe some with different tones in standard colors. Casual dress shoe wearers are looking for new and exciting bold colors so this is the perfect shoe type to deliver on that.

Finally, a dress shoe that actually feels like a sneaker!
Size: 8.5, Color: Dark Brown
I was honestly super skeptical about buying shoes on Amazon, especially "dress sneakers." Usually, they either look incredibly cheap in person or they completely destroy your heels within an hour. I am so glad I took a chance on these Bruno Marcs. I commute to campus and take the bus almost every day, so I end up doing a ton of walking. I needed something that looked sharp and put-together, but I absolutely refused to sacrifice comfort for a long day on my feet. These completely hit the mark. Right out of the box, there was zero break-in period—no stiffness, no pinching, and no blisters. They are incredibly lightweight, and the material actually looks premium, not like that shiny, fake plastic you sometimes get at this price point. The traction on the bottom is surprisingly good too, which is a lifesaver when I'm rushing to catch my bus on rainy mornings. If you’re on the fence, just get them. It’s rare to find a shoe that balances looking professional with feeling exactly like your favorite weekend sneaker. Easily one of the best wardrobe purchases I've made in a while!

High quality, perfect color and very nice price!
Size: 14, Color: Brown, Size: 14, Color: Brown
I bought this shoes for my husband's Christmas present, so he didn't try yet. So far, the color is perfect! I feel like he can wear this shoes with different outfits, for the price it seems hight quality, it is not heavy at all. The shoe features a soft, comfortable lining and the sole is perfect because it is non-slip.
