I wanted to make mine a bit wider, so I put some thick socks on, put the
Crocs in the dryer for a few minutes, then put them on. (I wore them for several hours, but I think you only need to wear them until they're cooled off.) This worked great for stretching.
I have no idea if it would work for shrinking. When I pulled them out of the dryer they felt thicker and much softer, so who knows? Give it a whirl.
