Quick answer: It depends on your feet. If they have lost feeling or had a sore, or you have artery disease in your legs, international foot care guidelines advise against knee high socks, so ask your doctor or foot care team first. Otherwise, choose a non-binding pair whose top stretches open easily and leaves only a faint line. Start with crew if your calves are wide.
Knee high diabetic socks show off a print from ankle to knee and keep tall boot tops off bare skin. The catch is the top band. It sits just below the knee, above the widest part of your calf, so the fit of the leg matters more than with a crew sock.
We make Mi Socks in crew and knee high, so weigh our view accordingly. Our own socks have their own section near the end.
What are knee high diabetic socks?
Knee high diabetic socks are non-binding socks that reach to just below the knee, instead of ending around the middle of the calf like a crew sock. Knee highs are also called over-the-calf socks. They share the features health groups look for in any diabetic sock: the American Diabetes Association (ADA) suggests socks that "fit well and aren't too tight," and NIDDK suggests "lightly padded socks that fit well" and says, "Do not wear tight socks or elastic stockings."
A non-binding knee high is not a compression sock, so check the label. Compression knee highs squeeze the leg on purpose, most at the ankle, as MedlinePlus explains. If a package lists a pressure in mmHg, it is a compression sock even if it also says "diabetic," so if you have diabetes, ask your doctor before you wear one.
The ADA suggests asking your provider about compression socks if you have weak leg veins, leg swelling or a past deep vein blood clot, or you walk or stand a lot. The NHS says compression stockings are not suitable if you have problems with blood flow in your arteries. With diabetes, let your doctor decide, and see diabetic socks vs compression socks.
Who are knee high diabetic socks good for?
Knee highs are a comfort and style choice. They tend to suit you if:
- You wear tall boots. A sock that ends below the boot top leaves bare skin for the boot to rub.
- You wear skirts, dresses or cropped trousers and want your legs covered, or want a print to show.
- Your ankles puff up more than your calves, and your doctor has already checked why. A knee high's band sits higher than a crew top, away from the puffiest part. New swelling with diabetes needs a doctor first (see below), and our guide on what to wear when your feet swell has more.
Who should start with crew or ask a doctor first?
Start with crew if your calves are full, and ask first if your feet are at risk.
- If you have lost feeling in your feet, have artery disease in your legs or have had a foot sore, ask your doctor or foot care team before you wear knee highs. For people at risk of foot sores, the International Working Group on the Diabetic Foot (IWGDF) 2023 practical guidelines advise against tight or knee high socks. The CDC says about half of all people with diabetes have some kind of nerve damage, and NIDDK warns that you may not feel a pebble inside your sock or a blister on your foot.
- If your calves are wide or very full, start with crew. A crew top usually ends below the widest part of the calf, while a knee high stretches over it all day. Our guide to socks for wide calves shows how to measure.
- If your doctor prescribed compression stockings, keep wearing them as directed. A non-binding knee high doesn't replace them.
- If a knee high already leaves a ring under your knee, size up or switch to crew. A HealthLink BC checklist says not to wear short stockings such as thigh-highs, knee-highs and garters, which hold up with a band around the leg.
How should knee high diabetic socks fit at the calf?
Snug enough to stay up, loose enough that you barely notice the top. Check these points on the first day:
| Where to look | Good fit | Too tight or the wrong size |
|---|---|---|
| Top band, just below the knee | Opens easily when you stretch it with two fingers | A red ring or deep groove under the knee after a few hours |
| Over the calf | Lies smooth, with a faint knit pattern at most | Rib marks across the widest part of the calf |
| When you sit | The top stays below the bend of your knee | The top folds or digs in behind the knee |
| Heel and toes | Heel pocket on your heel, room to wiggle your toes | Heel pocket pulled under your heel, or fabric folded over your toes |
| By evening | A faint line that fades soon after the socks come off | A groove that lasts, or skin that stays dented when you press it (show your doctor) |
Why a full calf feels it more: a knee high's top sits above the fullest part of the calf, so the sock stays stretched over it all day. A small study that measured 81 adults found the calf widest about 22% of the way down the lower leg, a few inches below the knee.
To check a new pair at home:
- Measure your calf at its widest point in the evening, since MedlinePlus notes that legs have the least swelling early in the morning. Compare it with any calf range the brand publishes.
- Stretch the top with two fingers. It should open easily.
- Smooth the sock up from the toe so the heel pocket lands on your heel. Don't fold or roll the top, which doubles it into a tighter band.
- Look at your legs when the socks come off. A faint line that fades soon is common. A deep groove means the band is too tight for your leg. See why socks leave marks on your legs.
With diabetes, check by eye, not by feel, because nerve damage can make you lose feeling in your feet (NIDDK). For the rest of the sock, see how diabetic socks should fit.
Crew vs knee high diabetic socks: which should you choose?
Choose by your calves, your shoes and what you wear. Research hasn't settled which length is better for people with diabetes: a 2026 systematic review of diabetic socks found "a notable gap in the literature regarding the recommended sock length."
| What to compare | Crew | Knee high |
|---|---|---|
| Where the top sits | Around the middle of the calf | Just below the knee |
| Stretches over the widest part of the calf | Usually not | Yes |
| Tall boots | The boot can rub skin above the sock | Covers the skin under the boot |
| How much of a print shows | A little above the shoe | Ankle to knee with skirts or cropped trousers |
| Lost feeling in your feet, artery disease in your legs or a past foot sore | Ask your foot care team which socks suit you | The IWGDF advises against knee high socks; ask first |
| Mi Socks prices for 1, 3, 6 and 12 pairs | $9.99, $21.99, $35.99, $64.99 | $9.99, $22.99, $36.99, $67.99 |
| A good first pick for | Wide or full calves, sneakers and work shoes | Tall boots, skirts and dresses, prints you want to show |
Still not sure? Wear one pair of each length on a long day before you buy a pack.
What should you check before buying knee high diabetic socks?
- A non-binding top. Look for "non-binding" or "no tight elastic," then do the two-finger test.
- A calf range, if your calves are full. Choose one that goes past your measurement, since a sock worn at its limit presses harder.
- Your size on the brand's own chart. Between sizes? Size up one, then check that the heel pocket still lands on your heel.
- A smooth toe. Turn the sock inside out. Any seam should lie flat.
- Light padding that still fits in your shoes. MedlinePlus tells people with diabetes never to buy tight shoes.
- A fabric that suits your sweat. Cotton feels soft but holds sweat; the ADA suggests synthetic fabric or wool to move moisture away.
- Prints you'll enjoy, plus a light pair. A sock you like is a sock you'll wear, and for daily foot checks the ADA suggests white or light-colored socks, which make blood or drainage easy to spot.
- A return policy for unworn pairs. Worn socks usually can't go back, so one pair is the cheapest test.
What are Mi Socks knee highs like?
We make Mi Socks, so weigh this section accordingly. Our knee highs are about prints and a gentle fit. They come in the same 7 colors as our crew: Black Stars, Grey Polka Dot, Dusk Blue Stripes and Purple Stripes, plus Black, White and Marble Grey.
The top band is knit loose, with no tight elastic ring, and is made to stay up without squeezing. They have a smooth flat toe seam and a terry-cushioned sole, in a breathable cotton-rich blend: 80% cotton, 13% polyester, 5% rubber and 2% spandex. If you react to rubber or latex, ask your doctor before you buy. They are non-compression socks in sizes M, L and XL, matched to shoe sizes on our sock size chart. Imported. We haven't published a calf measurement yet, so if your calves are wide, start with crew or choose a brand whose published range covers yours.
One pair of Mi Socks diabetic knee high socks is $9.99, the same as crew. Packs cost a little more than crew: 3 pairs for $22.99 ($7.66 a pair), 6 for $36.99 ($6.17 a pair) and 12 for $67.99 ($5.67 a pair). Packs come as a Prints Mix of stars, stripes and polka dots, a Classic Mix of black, white and marble grey, All Black or All White, and the 12-pack also comes Assorted, a mix of solids and prints.
A single pair ships for $4.95, and orders of $19 or more ship free in the US, so one crew pair and one knee high pair together ship free. You have 15 days after delivery to request a return of unworn, unwashed socks in their original packaging. The return label's cost comes out of your refund, unless your order arrived damaged, defective or wrong. Browse our non-binding socks in both lengths.

When should you see a doctor about your legs or feet?
- Call 911 for leg swelling with shortness of breath or chest pain (MedlinePlus).
- Contact your provider right away for new or worse swelling in one leg, or a swollen leg that is red or warm (MedlinePlus). With diabetes, the NHS advises an urgent appointment for swollen feet, ankles or legs.
- Call your health care provider right away if a cut, blister or bruise on your foot does not start to heal after a few days, or if skin on your foot turns red, warm or painful (NIDDK).
Check your feet every evening when your socks come off, with a mirror if you need one, as NIDDK suggests. Our diabetic foot care checklist covers the daily routine.
Frequently asked questions
Can diabetics wear knee high socks?
It depends on your feet. NIDDK says not to wear tight socks or elastic stockings, so the top must not squeeze. If you have lost feeling in your feet, have artery disease in your legs or have had a foot sore, the IWGDF advises against knee high socks, so ask your doctor or foot care team first.
Should knee high diabetic socks be tight at the top?
No. The top should hold the sock up without squeezing and leave no more than a faint line that fades soon. A red ring or deep groove under your knee means the band is too tight or the size too small.
Do men and women need different knee highs?
Go by your shoe size and calf measurement, not the label. In CDC survey data, men's calves averaged only a little wider than women's, about 15.5 inches against 15.
Why do my knee high socks roll down?
Usually the sock is too big, or the top has loosened with wear. Don't hold it up with a rubber band, which NIDDK advises against. If the heel pocket sits above your heel, try the next size down. Replace a pair whose top no longer holds.
Mi Socks are non-compression comfort socks, not a medical device or treatment. Check your feet every day and follow your doctor's or podiatrist's advice. More on our medical information page.
