How to make your compression socks last longer (and when to let a pair go)

You pull your favourite pair out of the drawer. It's been on three flights and more long Saturdays than you can count. This time it goes on a little too easily, and by lunch it's slouched down around your ankle. It hasn't done anything wrong. It's just tired.

A compression sock is working gear. The stretch that creates its gradient gets used every time you pull it on, and it wears down with every trip through the wash. Look after that stretch and a pair gives you a lot more good wears. Neglect it and even a well-made sock gives up early.

Our socks were built for hospital and clinic floors, where people wear their gear hard and wash it constantly. Here's what we've learned about making a pair last.

Where a sock's life actually goes

Every compression sock has elastane knitted through it. That's the part that springs back and keeps the pressure firmest at the ankle, easing off up the calf. Three things wear it out faster than anything else: heat, harsh chemicals, and being stretched too far for too long.

Heat is the big one. Hot washes, tumble dryers and irons all break down the stretch, and bleach does the same. The third one surprises people. A sock that's too small for your leg spends every wear stretched well past the shape it was made to hold, and elastic kept at full stretch for hours at a time loses its spring faster. So a pair in your actual size isn't just more comfortable. It's also not running at its limit all day.

The care routine that keeps them going

None of this takes much effort.

Wash cool. Under 30°C, with like colours.

Air dry. Skip the tumble dryer, the iron, the bleach and the fabric softener.

Don't haul them up by the cuff. Gather the sock down to the heel, get your foot in, then ease it up your leg. Yanking the top band is how cuffs go loose and wavy.

Travelling? A pair rinsed in cool water in the hotel sink, rolled in a towel to squeeze it out and hung over the shower rail is usually ready by morning. Much better than stuffing a worn pair in your suitcase until you get home.

Rotation is the easiest way to add months

Elastane needs a rest between wears to recover its shape. If you wear one pair every day, it never gets that rest. With a few pairs in rotation, each one gets a day off, so each pair lasts longer.

A simple way to set it up is one pair for each long day of your week, plus a travel pair that lives in your suitcase.

Built for the wash as well as the wear

A shift in a hospital or clinic is twelve-plus hours on hard floors, followed by a wash, and then it happens again. Every pair we make has to pass our twelve-hour shift test, worn on our own shifts before we sell it. That's why we reinforce the points that wear first and knit terry cushioning into the sole, so it doesn't pack flat. The socks are built for daily wear-and-wash cycles, and good care is how you keep that durability working for you.

Knowing when a pair has done its job

Even with perfect care, compression socks are a consumable.

A tired pair still feels like a sock. It just can't hold the pressure it started with.

These are the signs:

• It goes on noticeably more easily than it did when new.
• It slides or bunches at the ankle by midday.
• The cuff has gone loose or wavy.
• The heel or sole looks thin, shiny or see-through.

As a rule of thumb, plan to replace a pair every three to six months with regular wear. When you restock, measure your calf again before you order, because legs change too.

The honest bit

A fresh pair gives you back the fit a tired one lost. It won't fix legs that are telling you something else. If swelling hangs around, keeps coming back, or one leg is noticeably more swollen or sore than the other, talk to your doctor before you reach for a new pair of socks.

So next time you open the drawer, give your oldest pair a quick check. If it slides on with no resistance at all, it's earned its retirement.
