My husband has found these shoes to be reasonably comfortable for a long day on his feet. Not too warm, they didn't retain odor much, and a nice "looks good with everything" color. However, they're not very durable. After less than a year, the soles basically gave way. I could push on the bottom of the ball of the foot area of the sole and it flexed like a poorly inflated balloon, structure and support was absolutely shot. Holes started appearing in the tread almost immediately after. That said, I would recommend them 1) if you can get them at an insanely good price and/or 2) if you can't afford anything better---say when you're starting a brand new job and have to have them right away. Otherwise, save your pennies for a better brand.
My review of the Cat shoes is as follows: shoes where too tight causing both my feet to get blisters. My left foots back ankle was rubbed raw because some kind of piece of plastic was sticking out causing my ankle to bleed from being rubbed. Hopefully, this was just this pair of shoes. Sorry but I won't be purchasing them again. :(
