Stylish, comfortable, and a great price.
Size: 11, Color: Dark/Blue, Size: 11, Color: Dark/Blue
Can't beat the quality at this price. This is my 2nd pair, my last pair (in brown) lasting almost 3 years as a work shoe in a dusty warehouse. Nice and light. Fitment is true to size. Very good looking and comfortable shoe. I suggest insoles as the soles are a little thin and can be rough on a bad back. And they squeak on the floor after they age. But again, for the price you can't beat these shoes. Did, would, and will buy again.

Nice shoe, sizing information on this review
Size: 9, Color: Grey, Size: 9, Color: Grey
Ok, let's talk Breeze Mesh Sneakers by Bruno Marc (Grey)...... Firstly, they are nicely stylish appearance wise. They are lightweight (which I like). They feel comfortable and easy to walk in. I have not owned them very long, so I can't inform you on long term wear or how they feel after months of use. I own many pairs of shoes, mostly running type shoes. I needed a pair like these to wear in a more formal situation. Maybe with some dress pants or nice jeans. Now let's discuss the SIZING which is very important to me. Without a good fit, your shoes will never feel right when wearing. I normally wear size 9 in Men's. I seen someone mention that they 'run small'. I can do 9.5 in those situations, so I ordered 9.5. When they arrived and I tried them on, it was obvious they were too big. too much toe room in front. So I returned them for my normal size which is 9 Men's. Much better. AND, i still have toe room in front (no tightness). My suggestion to you is to order your normal size. The shoes feel like quality shoes and I feel that are a good purchase (for the price). The shoes came quickly. Bruno Marc is a good overall shoe. Hope this information helps.

Great shoes
Size: 10.5, Color: Dark Grey
I saw people wearing shoes like this in the office (maybe not the same brand), so I ordered a pair to see how they feel. They feel amazing. It's basically sneaker that look ok to be worn with pants and sport jacket. Fit is great, I ordered my usual size and they fit nicely.
Sole is thick enough to make them comfortable, not too thick to looks like a sport sneaker. Durability seems ok, wore them couple of times, so I can't really tell, but they seems like they can last long time.

These shoes adequately do the job they're meant to do
Size: 11, Color: Black, Size: 11, Color: Black
For shoes to wear daily for work, these are absolutely perfect. I give four stars simply because they are not 100% perfect; that is, they are a reflection of their cost and durability. With that said, these shoes are perfect for my role as a professor AND a person who walks half a mile from the train station to class and back 5x a week. Comfortable. Nice cushion on the heel. And they look really amazing - classy but not pretentious. I bought a second pair a week after the first just so I could have different colors, and it is likely I will get a third pair. For $40-ish dollars, they do the job they're meant to and they do it well. This picture shown are the originals I bought, but I also got the black pair, too.
