Quick answer: Follow the care label. For Mi Socks, that means machine wash cold on gentle, hang to dry, and skip bleach and fabric softener; air drying avoids the dryer tumbling that shrinks cotton. Replace a pair at the first hole or thin spot, or once the top stops staying up, and own enough pairs for a clean pair every day.
A diabetic sock has three jobs: stay soft, lie smooth on your foot and hold up without squeezing your leg. The wrong wash can undo that. A pair that shrinks grips harder at the top and presses on your toes. Here is how to wash diabetic socks, how long they last, when to replace them and how many pairs to own.
How do you wash diabetic socks?
Start with the care label on the sock or its package. The Federal Trade Commission's Care Labeling Rule requires the makers and importers of the clothing it covers to attach a care label with regular care instructions. If a label says not to bleach, take it seriously: the FTC requires that warning when every bleach on the market would harm the item with regular use.
Here is a simple routine. The wash, additive and drying steps are the care for Mi Socks; if your socks have a different label, follow theirs.
| Step | What to do | Tip |
|---|---|---|
| Before the wash | Turn each sock inside out | The inside is the side that touches your skin. Look at the toe seam and sole as you turn them. |
| Sort | Wash white and light pairs together, and dark pairs with darks | Keep your light pairs light. The American Diabetes Association (ADA) suggests white or light socks so bleeding or drainage is easy to spot. |
| Wash | Machine wash cold on the gentle cycle | A mesh laundry bag keeps pairs together. |
| Additives | Skip bleach and fabric softener | Measure the detergent the way the bottle says. |
| Dry | Hang to dry | Let them dry all the way before you wear them or put them away. |
| Put away | Turn them right side out, pair them and fold them flat | Check each pair for holes and thin spots as you fold. |
Can you put diabetic socks in the dryer?
Hang drying is the safer choice for a cotton-rich sock. In research by Cotton Incorporated, reported by Textile World in 2005, all-cotton knit fabric tumbled in a dryer with no heat at all shrank more than 20 percent after 45 minutes. Loads dried on hotter settings reached the same shrinkage, just faster. The tumbling, not the heat, did most of the shrinking, so a low-heat setting doesn't solve it. The researchers suggested tumbling no more than five minutes, then hanging clothes to dry.
A sock that shrinks gets shorter and narrower. The top band then grips your leg harder and the toe pulls across your toes, which is the opposite of what a non-binding sock is for.
Make sure every pair is fully dry before you wear it. The ADA notes that extra moisture can lead to skin breakdown and infections.
Can you wear diabetic socks two days in a row?
It's better not to. MedlinePlus advises people with diabetes to wear clean, dry socks every day, and the NIDDK says to choose clean, lightly padded socks that fit well.
- Change during the day if your socks get damp, from sweat, rain or a long shift.
- Use a fresh pair for bed. NIDDK suggests socks in bed if your feet get cold, and MedlinePlus says those should be clean, dry socks.
- Put every worn pair in the wash, even if it looks clean.
How long do diabetic socks last?
There is no fixed number of months. A sock wears out from use and washing, so it lasts longer when it shares the work with more pairs. Here is how often each pair gets worn and washed if you put on one clean pair a day.
| Pairs in your drawer | Times each pair is worn and washed in a year | Works for |
|---|---|---|
| 7 | About 52 | Weekly laundry, with no spare for a damp pair |
| 10 | About 36 | Weekly laundry plus two or three spares |
| 14 | About 26 | Weekly laundry with a fresh pair for bed or a midday change |
Wear thins a sock over time. A 2026 review of diabetic sock research describes an 18-week wear trial in which a terry-knit sock lost about 10% of its thickness and a flat-knit sock about 7%. The same review found that special finishes added to sock yarns tend to wear off with washing, so don't expect a finish to last as long as the sock. For more on cushioned soles, see our guide to padded diabetic socks.
How often should you replace diabetic socks?
Non-compression diabetic socks have no official replacement schedule, so go by what you see. The only interval we found from a health source is for compression stockings: MedlinePlus says to replace them every 3 to 6 months so they keep their compression and support.
Check your socks on laundry day. MedlinePlus notes that holes in socks can put damaging pressure on your toes, so a pair with a hole is done.
| What to check | How to check it | Replace the pair if |
|---|---|---|
| Heel, ball and toe | Hold the sock up to a window or lamp | You see a hole, or light shines through a thin spot |
| Cushioned sole | Pinch the sole between your thumb and finger | It feels flat or hard compared with a newer pair |
| Top band | Stretch it open, then let go | It stays stretched out, or the sock now slides down your leg |
| Size | Lay it next to a newer pair of the same size | It has shrunk, or the top now leaves a deeper line on your leg |
| Inside the toe | Turn it inside out and run a finger across the seam | The seam has twisted, frayed or turned rough, or loose threads catch your toes |
Don't hold up a stretched pair with a rubber band. NIDDK advises against it. Our guide on how diabetic socks should fit covers fit changes in more detail.
How many pairs of diabetic socks do you need?
Multiply the clean pairs you use in a day by the days between laundry loads, then add a few spares for damp days and slow drying. Hang drying takes longer than a dryer, so spares matter more.
- One pair a day, laundry once a week: about 10 pairs.
- A day pair and a bed pair, laundry once a week: about 17 pairs.
- One pair a day, laundry twice a week: about 6 pairs.
If your doctor has prescribed compression stockings, MedlinePlus suggests having 2 pairs, so you wear one while the other is washed and dried. For what a year of socks costs at different prices, see how much diabetic socks cost.
When should you see a doctor?
Your laundry pile doubles as a foot check. Light socks show stains clearly, which is why the ADA suggests them.
- Blood, drainage or a stain you can't explain on a sock: check that foot right away, and call your doctor or podiatrist.
- A cut, blister or bruise that does not start to heal after a few days, or skin on your foot that turns red, warm or sore: call your health care provider right away, as NIDDK advises.
- Any change in your feet: the CDC says to check your feet every day, even if they feel fine, and not to wait for your next appointment if you find a problem.
- Deep marks from socks that fit: if a loose top in the right size still leaves a deep dent, ask your doctor whether swelling is the cause.

What care do Mi Socks need?
We make Mi Socks, so weigh this section accordingly. They are non-binding diabetic socks with a wide, loose top band that stays up without a tight elastic ring, a smooth flat toe seam and a terry-cushioned sole. The fabric is 80% cotton, 13% polyester, 5% rubber and 2% spandex, so ask your doctor first if you have a latex allergy. Care is simple: machine wash cold on gentle, hang dry, and skip bleach and fabric softener. They are not compression socks and not a medical device.
For a full drawer, our value packs lower the price per pair: a crew 6-pack is $35.99 ($6.00 a pair) and a crew 12-pack is $64.99 ($5.42 a pair), or $36.99 and $67.99 in knee high. They come in crew and knee high, in sizes M, L and XL on our sock size chart, in solids and prints. Orders of $19 or more ship free in the US. Returns are for unworn, unwashed pairs within 15 days, so if you are new to our sizing, try a single pair ($9.99) before you buy and wash a whole pack.
Even well-washed socks wear out. See how often to replace socks for the signs a pair is done, and how many pairs of socks you need to keep enough clean pairs on hand.
Frequently asked questions
Should you wash new diabetic socks before wearing them?
That is up to you. If you do, follow the care label. Keep in mind that washed socks usually can't be returned, so check the fit with one pair first.
Can you hand wash diabetic socks?
Yes. Use cool water and a little detergent, rinse well, press the water out without wringing, and hang them to dry.
How do you wash compression stockings your doctor prescribed?
Follow your doctor's instructions and the label. MedlinePlus says to wash compression stockings each day with mild soap and water, rinse them and let them air dry.
Can you wash diabetic socks with other clothes?
Yes, with similar colors on the cycle the label calls for. Keep white and light pairs with your whites so they stay easy to read for stains.
