I need a pair of cheap houseboots (actually, a bunch of pairs); and so does my contractor and lots of other people).
I'm building a house, and there's dirt all around. Every time I need to come inside for something while I'm working out in the dirt, I have to stop and take my boots off (or else track dirt and sand onto my nice new cork floor). And then put 'em back on again when I go back out. A royal pain, both ways.
After I came up with this idea, my wife and I found a pair of big slip-on booties in a catalog--for 27 bucks! Not what I had in mind at all. What I need is a paper pair that'll last for a few trips into the house and then can be thrown away. A couple bucks a pair would be OK, but under a buck would be great.
Yes, there are hospital and cleanroom booties that one can buy for maybe 15 cents a pair if you buy a case of 300. But if you've got a handful of tools or something, you don't have two hands free to put 'em on. What's needed is something that one can slip one's boots into without using one's hands at all. They should have slightly raised backs, so that dirt doesn't just slide off the back end while you're walking. Kind of like large low-back bedroom slippers.
Housewives with kids would probably appreciate having houseboots in small sizes, too.
Reward: A lifetime supply? Small royalty if the idea really makes money?
