My wife had already purchased a XeroSox (http://www.xerosox.com/), but the opening was too tight to stretch over my splinted ankle without inducing severe pain. Once I got the cast it was no longer an issue. I've taken my first shower with the XeroSox. It works as advertised. My next hurdle will be to recover to a point where I can bear some weight on the leg with the broken ankle. Now I shower seated on a wooden stool, only standing for a brief time on my good leg.
