I know I read on here somewhere that you could put crocs in the dryer to shrink them if they are too big. What about the ones that aren't made by Crocs - an off-brand? I bought a really cute pair for dd3 from Avon but they didn't have her size - about 1 - 1 1/2 sizes too big. I was hoping they ran small. I would like to try to shink them. Any advice?
