I have owned these shuttle socks for almost 3 yrs and they are fantastic. They are to be worn inside the house and usually in the winter when the floors are cold. If you are diabetic or have cold feet or poor circulation these slippers are for you. I recommend a slightly larger size, since its advisable to first put on a pair of normal cotton socks and then slip into the Shuttle socks. I know we all are upset that everything comes from China, but until we get rid of Congress and the President we are faced with this problem.
