These are the first walking shoes I have been able to wear comfortably for a long time. They are wide enough across the widest part of the foot, so I don't get blisters or calluses. They similarly fit my narrow heel properly, again, no injuries. The insole is some time of gel, and it is VERY comfortable. I have been wearing them in my new job in retail, standing for a full 8 hours and my feet do not hurt. I am VERY happy with these shoes.
