Very comfortable. Bought them for walking. Also bought them because I have Mortons neuroma and need a sneaker with lower heel that helps keep pressure off ball of foot. Sizing is ridiculous. I wear a size eight shoe and usually a nine in sneakers or Nikes. Nine was way tight. Store did not have 9.5 but had 10. Tried it on and it fit. I think the reason is that sole extends back but when you put your foot in it doesnt go that far back and toes seem squished in the front unless you size up a lot.
