Available only from Hammacher Schlemmer, these open-toe compression socks feature convenient side zippers that make them easy to put on and remove, even for those with limited grip strength. The zippered design provides a large opening for slipping the foot into the sock. Once the stocking is secured around the heel and ankle, the top portion zips shut around the calf. Its cotton/polyester/spandex blend produces 15-20mmHG compression that helps reduce swelling and improve blood flow. The knee-high fabric won’t wrinkle or bunch, the zippers have an easy-to-grasp long pull tab.  Open-toe construction allows wiggle room for those with podiatric issues. Can be worn under clothing. Hand wash. Medium (5 1/2"-8 1/2" ankle, 7 1/2"-14" calf) or Large (6"-10" ankle, 9"-16 1/2" calf); if in-between sizes, order the next size up. One pair. Black or Nude. Open Toe.
