Sizing for men
| Size | US shoe | UK | EU | AU | Calf up to |
|---|---|---|---|---|---|
| S/M | 4 – 8.5 | 3.5 – 8 | 36 – 42 | 3.5 – 8 | 16 in / 40 cm |
| L/XL | 9 – 13 | 8.5 – 12.5 | 42.5 – 48 | 8.5 – 12.5 | 20 in / 50 cm |
When shoe size and calf size disagree, the calf wins. Compression is engineered around the circumference it stretches over: put a sock rated for a 15-inch calf on an 18-inch calf and you are no longer wearing 20–30 mmHg — you are wearing considerably more, in the wrong distribution.
How to measure your calf properly
- Do it first thing in the morning, before any swelling develops.
- Stand up with your weight evenly on both feet.
- Find the widest point of the calf — usually about a third of the way up from the ankle.
- Wrap a tape measure snugly around it, level, without compressing the muscle.
- Record the number in inches or centimetres, and measure both legs.
Under 16 in / 40 cm with a shoe size in range: S/M. Over 16 in: L/XL. Within an inch of the boundary: size up. No tape measure? Use a strip of paper and a ruler.

Muscular, athletic and larger calves
This is where most men's compression socks fail. A conventional sock finishes in a narrow elastic band roughly a centimetre wide, and that band has to generate all its holding force across that centimetre. On a cyclist's or a labourer's calf, the result is a groove by lunchtime and a red ring that lasts into the evening.
TrueFit ends in a wide comfort strap that spreads the same holding job over a much larger surface area, with a considerably bigger stretch range. That is the single reason most men who abandoned compression socks previously stay with these. If you still get a deep ring after 20 minutes, the size is wrong — swap it free within 30 days.
What they actually look like
Plain matte black. Ribbed knee-high knit, no beige, no medical branding, no visible gradient markings. Under suit trousers they read as dress socks; with jeans and boots they read as ordinary work socks; with shorts they look like sport socks. Nobody has ever asked a customer why they are wearing medical hosiery, because visually they are not.
Boots, desks and driving
- Trade, warehouse and site work — reinforced heel and toe for boot wear; see standing all day.
- Desk and office work — seated hours idle the calf pump exactly like standing does. Wear them through the day, off in the evening.
- Driving and haulage — long drives are the same problem as long flights, with the added pressure of the seat edge behind the knee.
- Flying — put them on before you leave home; full guidance here.
- Gym and running recovery — two to four hours after a hard session; see running and recovery.
Compression level
TrueFit is graduated 20–30 mmHg: firmest at the ankle, easing towards the knee. That is the standard non-prescription level for occupational standing, travel, swelling and symptomatic varicose veins. 8–15 and 15–20 mmHg are lighter options that most men on their feet find fade out before the day does; 30–40 mmHg is prescribed after assessment. The mmHg guide compares them properly.
Speak to a clinician first if you have peripheral arterial disease, uncontrolled heart failure, diabetic neuropathy or any open wound on the lower leg.
Care and lifespan
- Wash after every wear — compression fibres need to recover between wears.
- Cold wash, gentle cycle or by hand. A mesh bag prevents snagging.
- Hang dry. Never tumble dry: heat is what kills elastane and flattens the gradient.
- No fabric softener — it coats the fibres and reduces stretch recovery.
- Replace after roughly three to six months of daily wear. If a pair suddenly feels easy to pull on, it has lost its rated pressure.
