Love the look, but Narrow
Size: 10, Color: Marine Blue/Woodbury/Ivory
What is for my son-in-law, he loves them, but had to switch them out twice because they run very narrow. He doesn’t have a wide foot at all so be careful when you purchase. Other than that they are a good looking shoe and he really likes them.

Awesome value shoes
Size: 11.5, Color: Ivory/White/British Tan, Size: 11.5, Color: Ivory/White/British Tan
These white Cole Haan shoes are just what I hoped for, the color is a perfect off-white, somewhere between cream and pure white, which gives them a more refined look. The quality feels excellent, they’re very comfortable right out of the box, and the laces feel durable and well-made. They fit true to size with no issues. Based on this experience, I’ll definitely be buying more from this brand in the future especially at this price point.
