Great dress shoe
Size: 10.5 Wide, Color: Black
Wow. Very impressed with these. Would purchase again. Comfortable enough for my teenage son, my husband and I very impressed with their look. Great for any special occasion. Ours appear to be all leather. Even the sole. These will last a lifetime if cared for.

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.
