Compression only works when the sock fits. All you need is a soft measuring tape and two numbers: your ankle circumference and your calf circumference.
Legs swell over the course of a shift. Take your measurements right after you get up, before your feet have been under you for hours, so you size to your true resting leg.
Stand or sit with your foot flat. Wrap a soft tape around the narrowest part of the ankle, just above the ankle bone. Keep the tape snug but not compressing the skin, and write the number down in inches or centimeters.
Wrap the tape around the widest part of the calf, usually about a third of the way up from the ankle. Stay level all the way around and keep your weight evenly on both feet.
NursingRx knee-highs are sized primarily by shoe size, with ankle and calf measurements used to confirm the fit. Use the chart below to match all three.
If your shoe size points one way and your calf measurement points the other, go with the size that fits your calf. A calf band that is too tight rolls and digs in; too loose and the graduated compression cannot do its job.
Match your shoe size first, then confirm with your ankle and calf measurements.
| Size | Shoe size (US) | Ankle circumference | Calf circumference |
|---|---|---|---|
| S / M | 8 and below | 7.5" – 9.5" (19 – 24 cm) | 12" – 15.5" (30 – 39 cm) |
| L / XL | 9 and up | 9.5" – 11" (24 – 28 cm) | 15.5" – 19" (39 – 48 cm) |
NursingRx knee-highs are graduated from 14 mmHg at the calf to 16 mmHg at the ankle and 18 mmHg at the foot. Correctly sized, they feel firm and supportive at the foot and ankle and lighter as they move up the calf. They should never pinch, leave deep marks, or roll down at the top band.
Tested by nurses. Designed for long shifts.
