A zip to get them on, and an open toe once they are. Two problems solved in one sock.
The zip is for anyone who cannot wrestle a tight sock over a heel — stiff hands, a bad back, limited reach, recent surgery. The open toe is for anyone whose toes cramp, who has a bunion or a nail issue, or who simply cannot stand something gripping the front of the foot all day. It also means you can wear them with sandals.
15-20 mmHg
Moderate graduated compression — firmest at the ankle, easing toward the knee. The level most people actually want for heavy, tired, swollen legs after a long shift or a long flight.
Two pairs, so one can be in the wash.
Before you buy
If you are diabetic, have peripheral arterial disease, or reduced sensation in your feet, speak to your doctor first. Compression should feel supportive, never numbing.
