As previously mentioned, I lost the drawstring on one of my slippers (Capezio Juliette). Maybe because of this debacle, I decided to buy a pair of Bloch Pro-Elastics, which forego drawstrings all together.
...I really don't like them at the moment. They might be half a size too big, but the heel is really baggy. And the shoe is cut really low, so it feels like it's going to slip off, especially on my left thinner, smaller foot. There are also some weird gaps when I go up on demi.
I do like the way they hug my arch though (my previous slippers were a bit baggy there which I hated). I think the vamp is good for my long toes too. And the elastic around the top doesn't dig as much as drawstrings.
I'm going to wash them to see if they shrink. Then I'll either try sizing down or a new slipper. Maybe a stretch canvas shoe? My friend suggested leather for if I really want to mold the shoe to my feet, but I really hate the way leather squeaks. It makes my brain itch.
