"The uppers are buttery soft and the man-made soles (not sure what they are) are flexible enough that break-in is not required. I work in an office setting, but have a stand-up desk and only sit for about 30 minutes each day. I wore them the first time all day at work and a while afterwards and they are comfy. Look good too. Don't like that the laces are raw leather without metal tips and the "eyelets" are just holes punched in the leather without metal reinforcement. A bit challenging to lace the first time and I worry that the holes for the laces will enlarge over time. Really happy with them right now, will see how they hold up. DSW had a great price and shipped promptly."
