I can only wear the crocks with thick socks. If I wear them barefoot, something inside the crocks cut into my toes. I had some sores, so I just stopped wearing them. Then I put my foot back into them and felt the sharp pinching things attacking the tops of my toes again, so I immediately knew "go and put some thick socks on".

And I did so love these crocks. Oh well, now I know that next summer, I can't wear these. Back to my sandals.
