These Jobst UltraSheer compression stockings are made with new SoftFit™ technology which offers a superior design that prevents binding or cutting into the legs at the top band. This consists of a silicone yarn knitted into the inner welt which holds up stockings to prevent sliding, but without the added pressure and constriction. These stockings come in 15-20, 20-30 and 30-40 mmhg compression. Added to the list of features is seamless construction and seamless knitted edge at end of garment which is a great benefit for those that want to wear their compression stockings without notice.
