Taking a shower is a *** if you have a cast on. So I googled around and stumbled onto the Xerosox. It claimed that you could swim in a cast with this on and not get the cast wet. C’mon! But, I figured if it was half this good, surely I could take a shower and was worth the $38. Well, the darn thing works and I really think you could actually go in a pool–altho I wouldn’t try. It’s basically a rubber boot that you pump out the air to form a vacuum. As long as the vacuum holds, the seal is holding. Quite an amazing device and huge kudos to whomever invented it.
UPDATE:
The company changed their name to DryCorp (http://www.drycorp.com)
