A really nice pair of shoes
Size: 12 Wide, Color: Stucco
This is my second pair of Cole Haan shows and they're great. I waited until these were on sale so the price was amazing. The sizes run true and they fit perfectly. I have to purchase wide shoes because of my "boat feet"....lol They're very light so walking around all day is a lot easier They fit very well and are comfortable to wear, even right out of the box. The soles have solid traction. They look great and I get a lot of compliments at work when wearing them. For the price, fit and quality, I'll be buying more in different colors as they go on sale.

Comfortable and complimentary
Size: 11, Color: Brown
The shoes are very comfortable and easily broke in after two wears. I get several compliments on them daily, and others have purchased them after seeing mine. I also have the black pair, but the brown ones are my favorite. Sizing is true to size, an excellent value for your money, and they are lightweight and breathable. The soles are thick, which makes them extremely comfortable.

Nice but not ideal sizing.
These look nice. They do not have a traditional tongue, replacing it with some sort of elastic lining. They do fit larger than expected. I purchased wide since normally need that and it creates a bump just below the laces. Also, after size 11 there are only whole size increases. I feel an 11.5 regular would have fit better. They are pretty comfortable with a cushiony insole and thick sole.
