Nice looking Shoes
Size: 9, Color: Brown
These shoes are very nice. I never heard of the name Bruno Marc before, but I will say the shoes are extremely comfortable, and they look like similar high end shoes at the fraction off the cost. Very light and durable.

solid dress shoes for the price
Size: 12, Color: Black
solid dress shoes, specially when factoring in price. Fit to my size and work well for rare business dress days at my work. They aren't most comfortable dress shoes ever, but as long as not doing long walks in them, should be fine!
