Very comfy. I can walk and walk and walk in these. I've walked up a local mountain trail for two weekends in a row now, and outpace a woman 10 years younger than me! I have a desk job, and am in my 50's, just for context. I don't have health or foot issues, but I know that New Balance is supposed to be especially built for bad feet. Anyway, I really love these shoes, I would buy another pair in a heart beat.
