Comfortable Shoes

This is the second time I purchased this style of shoes. They are extremely comfortable.
They can be worn on casual and business events.

Great dressy sneaker to wear with business casual or jeans
Size: 11, Color: British Tan/Ivry
I got these for my husband to wear with jeans or business casual dress pants. They look sharp and professional and dress up jeans if you're going out. He says they fit comfortably and he can walk on them all day without his feet hurting. They are beautiful genuine leather so they don't get stinky. I got my husband's normal size and they fit to size.

Comfortable
Size: 9, Color: Black/Ivory
Most comfortable and roomy shoes I ever wore. Great for insoles. Looks nice too. The base of the shoe is a bit too thick but it’s fine.

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.
