Not A Walking Shoe
Size: 9.5, Color: Black/British Tan
In the photo online this shoe looks like it will be very comfortable. Kind of a classy Coach's Shoe. Also in the photo the heel portion of the sole looks thick and supportive. I bought them thinking they would be my go-to travel shoe. Wrong. This is not a comfortable shoe for extended wear. Short durations, OK. The main problem is that the sole is very thin and flexible in all directions. There is no, as in zero arch support, plus that thin heel means that you tend to rock back on your heels and it feels like you're pounding the pavement. I've worn once and I'm very disappointed. They look great, definitely high quality materials, but using them for the intended purpose of travel.... fah get about it. If you're looking for a good looking shoe to wear around the gym and you don't intend to use the treadmill, or elliptical, then this is the shoe you want. They would definitely be returned if I hadn't already worn them outside.

Very nice, but sizing is inconsistent
Size: 10 Wide, Color: Ivory/White/British Tan
All of these Cole Haan shoes are extremely well made and I like the styling. On the other hand, the sizing is very inconsistent and you may end up having to do a lot of returns trying to find the right size. Then if you get a different color of it, you may find the sizing different yet again. If you find your right zie, they are really nice shoes at a very reasonable price for the quality.

I love this brand. These shoes look and fit great!
Size: 13 Wide, Color: Black/White/Black
I love wearing Cole Haan shoes. This is the second pair I’ve owned and the style just gets me. I’ve worn these to work at a great professional job every day, not just casual Friday. I wear these when I head out shopping or to dinner. They are functional, comfortable, built for regular and bigger wider feet and comfortable. I am 6 feet tall and my feet have changed size over the years to me needing a wider shoe to relieve pressure on my toes and front wide porting of my foot. So the 13W feels great and still walks the same as a regular 14 but more comfort for me. They look amazing and qualify in some offices as dress shoes (depending on company rules they will justify a sneaker as a shoe with the tan colored “gum” sole as a sneaker) so check company policy. The black sole on this makes it look more dressy. I am switching out the laces to match my previous Cole Haan because I think the white shoelaces look better. As an adult, aside from my Kenneth Cole boots Reaction boots and Doc Marten’s these are the only shoes I will pay 3 digits for. This looks like skater shoes but with a more mature look.

I am certainly glad I found them and finally ordered
Size: 10, Color: Ivory/White/British Tan
A bit bulkier than my Stan Smiths Leather versions, but actually more comfortable. They seem to be a bit "clunkier" looking than a streamline Stan Smith, but it's a matter of style. It works for a change of pace. Gets or picks up dirt a bit, but cleans well, except the canvas part. Has lasted almost 6-8 months with very little signs of wear. Feels very secure in any type of weather or condition. Great alternative or addition to having a pair of Stan Smiths.
