I started a retail job a year ago-on my feet without a break for 6-8 hours a work day, on a cheap, hard floor. I never had foot pain in my life, and am a great walker, thin, in great physical shape, and even had worked in a hospital for 12 hr shifts (the floors were more merciful there though) without problems with other types of shoe. The pain from standing in retail was agonizing and debilitating, massage didn't help, wasn't eased by pain meds, and so bad some nights that I couldn't sleep. I was willing to try anything, and experimented with different shoes and insoles. I tried a pair of knock-off crocs, and - to my horror because they are such ugly shoes - they were the ones that worked. When they wore out, I bought these. Real Crocs turned out to be vastly superior to the knock-offs. Yes! What used to be pure torture is solved, thanks to these ugly contraptions. If you are challenged by the rigor of standing all day on a horrid floor, I highly recommend that you put aside aesthetics and give these light, roomy, giving shoes a try. I thought they were a gimmick. They are not. They really do take care of your poor feet and keep the pain away. (These Crocs are true to size, whereas other types are not.)
