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.
