"I'm wearing my fourth pair of these. On the plus side they're very comfortable and easy going. On the down side the "Memory Foam" insoles lose their memory pretty fast, especially if they get wet. After that there's very little cushioning. Also the synthetic "suede" insole fabric separates and crumbles off, especially at the heel. Yet I keep on buying more pairs because in their prime they're the most comfortable slip-ons I've found. Love/hate."
