They call them Shoovers. Electrolux is behind this idea. Looks like they'd add another inch to my height. They work on batteries. Except I can't find any to buy yet. The references I was seeing in Google to these needed housewifely appliances all dated to December, 2006.
Can you imagine wearing them to work, turning them on and then looking at your co-worker and saying, "These shoes really suck."
