I am a crocks girl too.....or anything that have a open back(slip ons)
I have a problem with my ankles hurting if to tight or ride in the wrong place on my ankle.

I often kick my shoes off so the ones that slip off and on work great for me. I too have a problem with feet getting to hot and that makes my whole body seem hotter.

I know not everyone walks as well as I still do but the bottoms of my feet hurt so bad I have to have on some kind of shoe. Even just foam flip flops as long as there is some couchion. For instance my hard wood floors....oohhh man....cant do it w/o some kind of shoe on.
Good luck girl.....I know its a pain to deal with....
