How to wash compression socks (and how long they last)

The five-step wash

1. Wash after every wear. Body oils and salt break down elastane. A wash after each wearing day actually extends the sock's life rather than shortening it.
2. Use cool or warm water, never hot. Up to 30 °C / 86 °F. Hot water permanently relaxes the elastic fibres that create the pressure gradient.
3. Mild detergent only. No bleach, no fabric softener, no oxygen boosters. Softener coats the fibres and stops them recovering their stretch.
4. Machine wash inside a mesh bag on gentle. The bag stops the cuff being stretched by zips and hooks. A delicate cycle is enough — compression fabric does not need agitation.
5. Air dry flat, away from heat. No tumble dryer, no radiator, no direct sun. Lay flat or hang over a rail; they dry in a few hours.

Machine or hand — which is better?

Hand washing is gentlest and takes about ten minutes: cool soapy water, gentle squeezing, rinse, then press the water out. Never wring or twist — that's what stretches a cuff out of shape permanently. Roll the sock in a towel and press instead.

Machine washing is perfectly fine if you use a mesh laundry bag and a delicate cycle. The bag matters more than the cycle: hooks, zips and jean rivets are what snag and stretch knitted compression fabric in a mixed load.

What ruins compression socks fastest

• Tumble drying. The single most common way people kill a pair. Heat relaxes elastane and the pressure never comes back.
• Fabric softener. Coats the fibres so they can't recoil.
• Bleach and oxygen boosters. Chemically attack the elastic content.
• Radiators and direct sun. Same problem as a dryer, slower.
• Wearing the same pair every day. Fibres need around 24 hours off tension to fully recover their shape.
• Long fingernails and jewellery. Snags in a graduated knit create weak lines. Use the heel-pocket method with the flat of your hands.

How long should a pair last?

With daily wear and correct care, plan on four to six months of reliable graduated pressure. Compression garments don't fail visibly — they quietly lose tension, so you keep wearing a sock that no longer does the job and conclude compression "stopped working". It didn't; the fabric aged.

Rough guide by usage:

• Every day, one pair: 3–4 months
• Every day, rotating 2–3 pairs: 6+ months per pair
• Travel and occasional wear only: a year or more

Five signs it's time to replace them

1. They slide on far more easily than they did when new.
2. The ankle no longer feels distinctly snugger than the calf.
3. They creep down during the day, no matter how well you smooth them on.
4. The knit looks thin, shiny or transparent at the heel or cuff.
5. Your legs feel heavy again by evening despite wearing them all day.

Storage and travel

Fold them flat rather than balling one inside the other — the classic sock ball stretches the cuff every single time. Store somewhere dry and out of direct sunlight. For flights, pack a clean pair in your carry-on and put them on before you board; our travel guide explains why the timing matters.

Bundle pricing

Because compression is a consumable, most wearers buy multiples rather than replacing single pairs three times a year.
