Beware.  I had good luck previously with Dr. Scholl's support socks ordered thru Amazon.  The one had liked was a nylon that stretched nicely.  It has been out of stock now for many months.  So I ordered this Dr. Scholl's version, material sounded about the same, ordered the larger size and unfortunately ordered two pairs thinking these products all the same.  Wrong!  My guess is the manufacturing is constantly jobbing these out to whichever sweatshop works for one cent an hour cheaper than the last one.  As soon as I received these socks I felt they had ridges for support meaning they did not stretch evenly.  It was with great effort I managed to get them on.  An hour after wearing them, one bunched up above the ankle, not a lot, maybe two inches down to one.  That was enough.  Like a torniquete it cut my circulation nearly off and left a nasty red welt when I finally got them off, also huge effort.

Okay so now I have a brand new unopened pair in the box and a second pair worn an hour to ligature my leg.  But, no returns.

all I can say is if you buy this product, buy only one pair to be sure they fit you.  Even better, buy another brand.
