Sizing Wear & Care

For the perfect fit, take a quick measurement of the widest part of your calf. Our compression socks are expertly designed to provide the ideal level of compression for their purpose. If your calf measurement is between sizes, go with how you prefer your compression socks to feel. If you prefer a firmer compression, go with the smaller size.

How to Measure Your Calf

  1. Measure in the morningSwelling is usually at its lowest first thing, so it's when you'll get your truest reading.
  2. Find the widest pointWrap a soft tape measure around the fullest part of your calf, flat against your skin, snug but not squeezing.
  3. Match your sizeFind your number in the calf size rows, then use your shoe size as a second opinion. If they don't quite agree, your calf gets the final say.
Why mornings?

As the day goes on, gravity gently draws fluid down into your lower legs, so your calves can measure a little larger by the evening. That daily ebb and flow is exactly what graduated compression is designed to support. Measure before it begins and your socks will fit the way they're meant to from the very first wear.

No tape measure handy? A piece of string and a ruler work just as well.

Why We Start With Your Calf

We always recommend going by your calf measurement rather than your shoe size, because it's the number that decides how well the compression actually works for you. Every pair we make is unisex, so this chart works for everyone. Sitting between sizes, or just want a little reassurance? Here's what we're asked most often.

Between Sizes?

It really comes down to how you like them to feel. The smaller size gives you a firmer, more supportive hold, while the larger one feels a little lighter. If you're right at the top of a range, that size is usually still your best match.

Calf and Shoe Size Don't Agree?

It happens more often than you'd think, and it's completely normal. Go with your calf. That's where the compression does its most important work, so it's the fit worth getting right.

Wide or Narrow Feet?

Nothing to worry about here. The foot is knitted to stretch and move with you, so it settles comfortably into your shape. It's one more reason we let your calf lead the way.

Top Band Feeling Tight?

Have a quick look at where it's sitting. The band is designed to rest about two finger widths below the crease behind your knee. Pulled up higher, folded over or bunched along your leg, the pressure gathers in one spot and can feel much tighter than it really is.

First Time Wearing Compression?

Welcome aboard. You'll feel them firmest around the ankle, easing off gradually towards the knee, which is exactly how graduated compression should feel. Snug is a good sign. If you ever notice pain, numbness or tingling, take them off and drop us a line.

Pregnancy?

Congratulations! Measure your calves as they are now, since things can change from week to week. We'd also suggest a quick chat with your GP, midwife or obstetrician to make sure Class 1 compression is right for you.

Our shorter styles finish at or below the calf, so there's no need to reach for the tape measure. Your everyday shoe size is all it takes to find your fit.

Finding Your Fit

Every pair we make is unisex, so this chart works for everyone. A few things we're often asked:

Between Sizes?

If your shoe size sits right on the line, think about how you like them to feel. The smaller size gives a firmer, more supportive hold, while the larger one feels a little lighter.

Shoe Size Varies by Brand?

It happens to all of us. Go with the size you wear most often in your everyday trainers or work boots.

Wide or Narrow Feet?

Nothing to worry about here. The foot is knitted to stretch and move with you, so it settles comfortably into your shape.

First Time Wearing Compression?

Welcome aboard. A snug, supportive feel is exactly what you're after. If you ever notice pain, numbness or tingling, take them off and drop us a line.

Care & Maintenance Guide

A little care goes a long way. Look after your BIOSx socks and they'll keep looking after you, wash after wash.

Wash Gently

Hand washing after each wear is best. Prefer the machine? Pop them in a mesh bag on a gentle warm cycle, no hotter than 30°C, with similar colours.

Keep It Mild

A mild detergent is all they need. Leave out the fabric softener and never use bleach, as both break down the fibres that give your socks their hold.

Air Dry

Give them a gentle squeeze rather than a wring, then let them air dry. In a pinch, a tumble dry on low heat (below 30°C) will do.

Keep Them Out of the Sun

Never dry them in direct sunlight or on heaters and radiators. High heat is the quickest way to wear out the elastic fibres.

6Months

Even with the best care, compression naturally eases over time. We recommend refreshing your pairs every six months so you're always getting the support you came for.

BIOSx Rapid Recovery Compression Socks

Fantastic socks. I purchased the BIOSx Rapid Recovery Compression Socks and they are great. Very supportive and they are quite easy to put on. They really do reduce the heavy leg/ aching feeling I use to feel without them. I highly recommend the Rapid Recovery Compression Socks if you are looking for firm supportive socks that do work.

Really do work

Needed new compression socks as l have had knee surgery and need them to keep the swelling down and to help with potential blood clots. When they arrived l could tell they are of a very high quality and they are fantastic. Not only have they helped the swelling but they have also helped with my sciatica pain down my calf on the other leg. My old compression socks don't even come close to these. Extremely happy and have comfort knowing what to expect the next time l buy again.

Feedback and review of these socks
I am a quadriplegic and suffer with fluid retention
These socks are great but do not seem long enough. I purchased them based on my shoe size
And they fit very well and comfortable. They just can’t be pulled up to just below knee joint and this causes some puffiness in that area. Overall very good socks just make sure you double check l your sizes for correct fit

What a pleasure.

After more than 50 years of being on my feet most of the day at work what a pleasure it was to slip on the L2 compression socks (who was to know I had a large calf!)

Like a well used pair of gloves, they fitted nicely over my feet providing comfort and support, I particularly liked the support on my Achilles.

No more of my feet swelling, discomfort or that heavy feeling in my boots, even seems to reduce the tingling/numbness you get from years of standing.

I also like the way they keep their shape, bleary eyed first thing in the morning it’s so easy to slide them over my feet with out having to think

Great quality compression socks

I’m a teacher and on my feet all day. These keep the swelling away and my feet feel way less tired. They feel snug but not suffocating. The wide toe feature is surprisingly very comfortable. I can spread my toes naturally, which makes my feet feel less cramped. So far have been great in the wash.

Bought them because my podiatrist recommended compression, but I didn’t want to look like I was wearing medical gear! These nailed it 🙈. Stays up and legs feel noticeably lighter.

Best and most versatile compression socks ever!

Best Compression Socks I own! I wear them all the time! My legs feel much lighter and I feel like I can go harder at the gym when I have them on. You can really feel the quality difference as soon as you put them on. I would 100% recommend these to anyone who is after some good quality compression socks that they can wear daily.

I’ve got the black Everyday Compression Socks and honestly, I wear them all the time. They’re super comfy and give my legs just the right amount of support. I feel like they help me push that little bit harder at the gym, and when I go for runs, my legs don’t feel as heavy — they just feel lighter and fresher. I didn’t expect to love them this much, but now I don’t want to train without them.
