tyvex bootie

A few years ago I was going to do a trip that had a number of knee-deep stream crossings for the first day. With thoughts of keeping my boots dry, I fashioned some tyvek slippers to wear through the water. I couldn't figure out a good way of keeping them on tight, so I simply used three big rubber bands per foot. That worked pretty good until I was about at the middle of the first stream. There, the sharp rocks on the stream bed destroyed the rubber bands, and the first slipper took off downstream.

That is not the way I intended to lighten my load.

–B.G.–

you didn't mention snow, but if you're thinking it, snow will abrade and shred tyvek quickly. I know; I tried & failed with mukluks of cut-down croc bottoms & tyvek uppers. Tyvek would be uber slippery on snow as a sole. Cabin use at best (with foam underfoot). Or treading lightly & shortly in summer.

I intend them for cabin use and quick jaunts to the outhouse on ski trips instead of a dedicated, heavier and expensive bootie cover. Not for use outside around camp. I'll experiment on my ski trip next week. Only use will tell if these are suitable.

You could glue some strips of "toughtek" on the sole to add a little grip or even a full sole of the stuff. It's quite resilient but will add a bit of weight if you cover the whole sole. Quest sell it (http://www.questoutfitters.com/miscellaneous.htm#TOUGHTEK%209000) and other outlets under other names. Quest's used to have a bit of stretch (I think the fabric base was knit) but the last piece I got was woven and non-stretch. This is better if you're walking on it because there's less tendency for sharp objects to penetrate it, plus it adds to the "structure" of your sole IMO…
By the way, glue (contact cement/seam grip) sticks very well to the fabric backing but NOT to the textured PVC "rubber" surface I find).
