For tradespeople, farmers and others who frequently need to cover and uncover their shoes (to protect interior surfaces from mud or worse), disposable booties are an unsustainable solution. They're also a pain to take on and off. This reusable and automatically-wrapping design seems much better:
I've been searching for something like this for a long time. On our free-range farm, I inevitably step in the shit of some animal on a daily basis, and pulling my boots off and on every time I need to go back inside to retrieve something gets old.

(Lastly, I was not able to find what company or designer invented these. There are tons of variants on the market. It's possible they were invented by a fellow named Joel Fersaci, whose Step in Sock model is featured in the video above.)
