Plus Size Socks: How to Find Socks That Fit Fuller Calves, Ankles and Feet

Quick answer: Plus size socks have extra stretch or room in the leg, the ankle and sometimes the foot, so the top doesn't dig into a fuller calf. Measure your calf and ankle at the end of the day, compare the numbers with each brand's published stretch, and start with a crew length, whose top sits lower on the leg. Bariatric socks are the roomiest kind, made for heavy swelling, and swelling that is new or in one leg needs a doctor.

Most socks are sized by shoe size alone, so every pair in a size has the same leg width whatever your calf measures. If cuffs leave deep rings, ribs press into your calf or socks roll down to your ankle by lunch, you may need a roomier leg, not a bigger foot. Here is how plus size, big and tall and bariatric socks differ, how to measure, and how to look after the skin under them.

What are plus size socks?

Plus size socks have extra room or stretch in the leg and ankle, and sometimes in the foot. There is no industry standard, so each brand decides what its label means. These are the labels you will see on roomy socks:

Label What the brand is adding What to check
Wide calf Room in the leg and top band A calf measurement, such as "stretches to" a number of inches
Extra wide or extra roomy More fabric in the foot, ankle and leg. Cosyfeet, for one, says its extra roomy socks are made with more material throughout. Stretch figures for the foot as well as the calf
Big and tall A larger size for bigger feet Whether the leg is any wider, not just the foot bigger
Bariatric The most room, for heavy swelling or bandaged legs Calf and foot stretch, and whether it will slide down on a slimmer leg
Non-binding A loose top band that stays up without squeezing How the top feels when stretched, and any published calf range
Compression socks your doctor prescribes Pressure on purpose, firmest at the ankle A pressure in mmHg on the package means it is a compression sock, so ask your doctor first

How do you know if regular socks are too tight for your legs?

A faint line that fades soon after your socks come off is normal. These signs mean the sock is too narrow for your leg:

  • A deep ring where the top sat, still there long after the sock comes off.
  • A rib pattern pressed into your calf, which means the whole leg of the sock is stretched tight, not just the top.
  • Skin that bulges over the top band.
  • A top that rolls over or slides down to the narrowest part of your leg.
  • A hard pull to get the sock over your heel and the top of your foot.

If your toes feel squeezed or the heel pocket is pulled under your heel, the problem is the foot, not the leg. Our guide to socks for wide feet covers that.

How do you measure your calves and ankles for socks?

Use a soft tape measure in the evening, sitting down. MedlinePlus notes that your legs have the least swelling early in the morning, so an evening number is the one your socks have to fit. Measure both legs and use the larger number.

Where How What it tells you
Calf Around the widest part, keeping the tape level Whether a knee high's leg, and a crew top on a lower calf, will fit
Ankle Around the narrowest part, just above the ankle bones Where a slipping sock will end up, and how roomy the ankle needs to be
Heel and instep Around the back of your heel and the top of your foot, with your foot flexed The tightest loop a sock has to pass over when you pull it on

Then compare your numbers with the brand's chart. A "stretches to" figure is the most the sock will open, and a sock worn near its limit presses harder, so choose a range that goes past your number. Our guide to socks for wide calves shows the full calf method and the calf ranges some brands publish.

Crew or knee high: which is better for bigger calves?

For a first pair, crew is usually easier. A crew top sits around the middle of the calf, often below its widest part, so the sock doesn't stay stretched over the fullest part of your leg all day.

A knee high top sits just below the knee, close to the crease behind it. MedlinePlus lists the backs of the knees among the warm, moist places where intertrigo, a skin fold rash, tends to form, because two skin surfaces rub or press together there. If a knee high top sits in that crease, rubs, or leaves a ring, switch to crew. Knee highs still make sense under tall boots and skirts.

What are big and tall socks?

Big and tall is a men's clothing label, and on socks it mostly means bigger feet. DXL, a big and tall clothing chain, says its big and tall socks are designed for larger men's shoe sizes, and describes them with ribbed-knit cuffs. The same store sells a separate extra-wide crew sock, a sign that the big and tall label alone doesn't promise a roomier calf. Check the leg as well as the foot. Whatever label you buy, your sock size comes from your shoe size, not your clothing size.

What are bariatric socks?

Bariatric socks are the roomiest kind of sock, made for heavy swelling and bandaged legs. Interweave Textiles, which makes hospital socks, describes its bariatric gripper socks as the largest size in its range, with a wider ankle, and says they stretch to 64 cm (about 25 inches) around the calf and 44 cm (about 17 inches) around the foot. It says the extra room is there for swelling, bandages and larger legs and ankles. The Extra Wide Sock Company says its one-size Beyond Extra Wide Bariatric sock stretches up to 30 inches in the calf, for very wide or swollen feet, ankles and legs.

A bariatric sock gives room. It doesn't squeeze, and it won't make swelling go down. If your legs aren't very swollen, one can be too big: spare fabric slides down or folds inside your shoe, and a fold presses into your skin. For milder evening puffiness, a non-binding sock is the simpler first try; see the best socks for swollen feet.

How do you look after the skin under your socks?

Skin that stays warm and damp where it rubs gets sore more easily. MedlinePlus says intertrigo is most common in people who are obese and forms where skin surfaces rub, including between the toes. At home, it suggests separating skin folds with clean gauze or a dry towel and wearing loose clothing in fabrics that draw moisture away from the skin.

  • Dry between your toes after washing, as the American Diabetes Association advises.
  • Moisturize dry skin, but not between your toes. MedlinePlus suggests lotion, petroleum jelly, lanolin or oil on dry skin, and none between the toes unless your provider says so.
  • Put on clean, dry socks every day, as MedlinePlus advises.
  • Skip anything tight. For legs with lymphedema, MedlinePlus suggests cotton socks, clean and moisturized skin, and no stockings with tight bands.
  • Check your feet daily, even if bending is hard. The CDC suggests a mirror or a family member's help if you can't see the bottoms of your feet.

Don't hold up a loose sock with a rubber band. The NIDDK advises against it.

When should you see a doctor?

A roomier sock can hide a mark without fixing what causes it. Get checked for any of these:

  • Call 911 for leg swelling with shortness of breath or chest pain, as MedlinePlus advises.
  • Contact your provider right away about new or worse swelling in only one leg, a swollen leg that is red or warm, or a fever (MedlinePlus).
  • With diabetes, don't wait. The NHS lists swollen feet, ankles or legs in someone with diabetes as a reason for an urgent appointment.
  • Skin that dents when you press it is a sign of fluid buildup, the NHS says, and it advises seeing a doctor if swelling hasn't improved after a few days or is getting worse.
  • Swelling with a heavy, aching feeling, hard or thickened skin, skin folds or fluid leaking through the skin. The NHS lists these among the symptoms of lymphoedema (lymphedema in the US), and MedlinePlus tells people with lymphedema to contact their provider if shoes get tighter or swelling lasts longer than 1 to 2 weeks.
  • Large lower legs on both sides while your feet look normal, especially if they feel heavy or tender or bruise easily. The NHS describes this in lipoedema, a build-up of fat in the legs that is more common in women and, it says, is not caused by being overweight. Ask your doctor about it.

If your doctor has prescribed compression stockings, keep wearing them as directed.

Do Mi Socks come in plus sizes?

We make Mi Socks, so weigh this section accordingly. They aren't sold as a plus size or bariatric line. They are non-binding diabetic socks with a wide, loose top band that stays up without a tight elastic ring, in crew (ends mid-calf) and knee high (just below the knee), sizes M, L and XL on our sock size chart. We don't publish a calf stretch yet, so if you need a guaranteed number, choose a brand that lists one.

Each pair has a smooth flat toe seam and a terry-cushioned sole, in 80% cotton, 13% polyester, 5% rubber and 2% spandex; ask your doctor first if you have a latex allergy. They are not compression socks and not a medical device. You can see both lengths in our wide calf collection. One pair is $9.99, and orders of $19 or more ship free in the US, so any two pairs ship free. Returns are for unworn, unwashed pairs within 15 days.

Frequently asked questions

What size socks should I buy if I wear plus size clothes?

Go by your shoe size and your calf, not your clothing size. Find your size on the brand's chart, then check its calf range against your evening measurement.

Do plus size socks stay up?

A pair in the right size usually does. If a roomy sock slides, it may be too big for your leg, or the top may have stretched out with wear. Try the next size down or a crew length before reaching for anything that cinches.

Can you wear bariatric socks over bandages?

Some are made with room for bandages, as Interweave describes. If your legs are bandaged, follow the advice of the nurse or doctor who applied them.
