I'm wearing a very comfy pair of new Pure Care Circu-Care graduated compression socks to test out. $4.95. Black, warm, thin enough to work as trouser socks. Just enough compression to keep the ankles and calves from pooling even slightly. Cotton-acrylic blend, moisture wicking (very important for foot care and diabetics), promotes leg circulation, antimicrobial odor control. Found them in the hosery section of the grocery store.
