I could have used a few pairs of these in Morocco - as well as disposable slacks, socks and shoes for a couple of the muckier places we visited (let's just say that this "muck" was rather questionable and definitely had it's own distinctive odor!) Many people in our group threw good clothes and shoes away afterwards. We tossed all of ours - shoes and all, in a bathtub full of hot soapy water as soon as we got back to the hotel. But if we ever go back, disposable would be the safest way to go!
