Perfect casual Friday shoe with great comfort and style
Size: 10, Color: Optic White/Egret
These have quickly become my go-to shoes for casual Fridays at work. The fit is true to size, and they’re both comfortable and stylish without trying too hard. They pair really well with jeans or khakis, so they’re easy to dress up or down depending on the day.

Good quality and looks great, the only complaint is the lace is a bit short
But size is good and color is perfect too.

Narrow and small
Size: 10.5, Color: Black/City Skyline/Egret
I mostly chose these due to the foam rubber soles, as I was looking for a more comfortable sneaker. They are more comfortable and the quality looks decent, too, although I wish the leather wasn't so shiny.
The fit is quite narrow, and while they're okay for my narrow feet, I still wonder if the wider fit would have been better.
This is my 2nd pair of Cole Haan sneakers and the first were too small. So this time I ordered the next size up and the fit is not much different, so I'd say they run small all around. Despite that, they're big enough and are still quite comfortable.
Finally, the laces are too short. This is probably by design, so they're not dangling around, but I find them difficult to tie. They're nice, waxed laces, but they just need to be long enough to work with.

Stylish and Comfortable
Size: 12, Color: British Tan
Young professional son loves them! They are very comfortable and stylish. They fit well with the new "business attire" standards and work well for going from work day to evening social.
