I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn’t work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I’d gladly replace if it broke.
I was as anti-croc as you can get until I tried a pair on. For house slippers, yard work, and grabbing the mail, they’re absolutely amazing. I won’t be caught dead in public with them though. If Croc made an insole they would sell like hotcakes. They’ve perfected their arch support and rebound.
