Overall, others give this:
Back in November I had a seasonal job working in a wreath factory, walking around on hard concrete for 8 hours a day. One morning, I had stepped in some dog **** and didn't want to wash my shoes, but had to leave for work at 6am. Since it was "holiday' hours, KMart was open and I was able to buy these shoes to replace dog doo'ed shoes. These shoes weren't bad, they lasted a solid month on concrete. They were covered in sap and surprisingly washed off quite well by a Mr Clean Magic Eraser. I had finally broken them like a bad pony, so I kept them around for working out at the gym (because you know, the new year or resolutions started right after my seasonal job). The shoes help up just fine, for a solid 6 months. It's definitely time to replace them....2 months ago. The cushion seems non existent now, but better than walking around barefoot. I would definitely get another pair in a pinch.
