Great Deal!
Size: 10, Color: Marine Blue/Bt Tan
I got these on sale for a really great price, and my son-in-law absolutely loved them. He was so happy when he opened them - he only wears Cole Haan shoes because he has a wide foot and he’s on his feet all day as a car sales man. The brown and black in the design makes them super versatile, so he can wear them with just about anything. They look great, feel well made, and were definitely worth it.

Really love these, but fit can vary.
Size: 8.5, Color: Navy Ink/Woodbury
I love these sneakers, but the fit came in different on the second pair. First pair were perfectly comfortable and very light. Second pair I bought in the same size came in very tight. The sole is the same size, visually they're identical, but the newer ones are much tighter on the foot. I wish I had checked closely when I bought them (was afraid they'd disappear so bought and stashed them without trying on). I've now worn them for months and they're still tight. I switch between the two depending if I am prioritizing comfort or the newer looking ones for work. Even the older ones have held up very well visually and structurally after 2 years. There is minor folding at the top, but since the color is dark and material is soft, it's hardly noticeable. The Navy knit and white sole still have great contrast and are not discolored.
