Very stylish and comfortable. I love how light they are because I’m on my feet all day. The black leather is very deep and very rich. The elevated sole gives me a tad more height, too…which I like. And yes, they’re slip ons. Don’t let the laces fool you. For under $40, these shoes are a strong value to consider…

I feel I’m walking on clouds

Size: 10, Color: Brown

I’m on my feet 6–8 hours a day working at the dealership, constantly walking the lot and helping customers—and I’ve gone through a lot of shoes trying to find something that actually holds up. These Bruno Marc MaxFlex Dress Sneakers honestly surprised me. They look sharp and professional enough for work, but feel more like a comfortable athletic shoe than a stiff dress shoe. From day one, there was no break-in period, no soreness, just all-day comfort. I feel I’m walking on clouds! If you’re in a job where you’re standing or moving around a lot but still need to look polished, these are hands down the most comfortable work shoes I’ve owned.

Not as expected

Size: 11, Color: Light Brown-pu

Unfortunately I ordered mine before the last review that said these are slip-ins. I'm not understanding that sock thing. It makes it harder to put the shoe on (So opposite of a slip-in) And it pulls your sock down (pictures show them wearing one) constantly when you're walking. And apparently the shoelaces are just for looks? But they're so long you have to tie them anyway, and as someone said the laces are bad. Skinny wax. I'm going to give this three stars though because they are very comfortable. So at this point in time I don't know if I'm going to return them (I got brown) as there aren't too many sneaker dress shoes (arch support) there's dress shoes that are more comfortable (but not sneaker comfortable).
