Got the tights bought as support tights during pregnancy, since I've been struggling with water retention and it was explained to me in medical supply stores that stockings from 70 have been supportive effect. Since I usually clothes and shoes size 38, I ordered size M. Unfortunately, the legs of the tights are cut loose, that although they are comfortable but have no effect stüztende. Too bad for me - as a normal opaque tights but quite usable.
