Saran Wrap on my feet?

Yeah, I actually tried this the other night. It was raining here in Cincinnati, at times pretty hard, but I really wanted to get out and put in a few miles. Well, a night or two before that my wife asked me if I'd ever wrapped my feet in Saran Wrap in order to help keep them dry. Apparently she's read this somewhere. I thought it was kinda silly to even consider when she first asked me. But now I was wanting to run, the rain was coming down, and it didn't seem like it was going to stop anytime soon. Maybe I need to consider this a little more seriously. Hmmmm......

I learned that wrapping your feet isn't all that easy, but I managed. I made sure to wrap beyond my toes, so I could fold the extra over, in order to help keep water from seeping in that way. I grabbed some old running shoes, and I slipped my foot into it. It kinda felt like I'd ripped through it. I took it out, looked it over, and realized I hadn't. Just a strange feeling.

I went out and tried to run through every puddle I could find. If I was going to test this, I might as well do it right. When you go through the puddle, you get this weird cold sensation from the water. But surprisingly, my foot didn't seem to be getting wet. Very cool! I ran 6 miles that night, and my shoes were soaked. But at no point could I feel any water squishing b/w my toes. When I got home, the Saran Wrap was still wrapped around my foot, and my socks were no more wet than normal. The real tell-tale sign for me was my skin. It didn't have the cold, wet, clammy feel to it. I actually think this worked. Well enough that I'll certainly do it again.

So that led me to wonder...why hasn't anyone invented "Saran Wrap booties" for runners to wear over their socks in rain & snow? I'm picturing a sock shaped baggie, with a piece of tape, like on baby diapers, at the top, to cinch around the lower leg to help keep water from coming in at the top. Or does such a product exist? Seems like it would. I can't possibly be creative enough to invent anything.
