- Silicone single-loop big toe spacer. Best for: Daytime use in shoes for rubbing between the big and second toe. See options on Amazon
- Gel spacer with bunion shield. Best for: A bump that rubs on the shoe as well as crowded toes. See options on Amazon
- Five-toe spreader for rest. Best for: Stretching the toes apart while sitting or relaxing barefoot. See options on Amazon
- Wide toe box shoes. Best for: Anyone wearing a separator during the day. See options on Amazon
What a toe separator does for a bunion
As a bunion develops, the big toe drifts toward the second toe and can press on it or ride over it. A separator, also called a toe spacer, is a small wedge of silicone or gel that sits in that gap. FootCareMD, from the American Orthopaedic Foot and Ankle Society, describes it as a spacer to maintain the gap between the big toe and the second toe. AAOS lists toe spacers among nonsurgical treatments.
The aim is comfort: less rubbing between the toes, less crowding of the second toe, and perhaps a slightly better resting position. FootCareMD says nonsurgical treatment focuses on relieving symptoms and slowing progression, not on reversing the bunion.
What the evidence shows
The clearest study is small. Researchers writing in the ASEAN Journal of Rehabilitation Medicine followed 40 people with moderate bunions, defined as a bunion angle of 20 to 40 degrees. They wore a prefabricated silicone toe separator in proper shoes for 6 hours a day for 12 months.
- Pain at the big toe joint fell significantly by 12 months.
- The bunion angle did not progress.
- About 60% had minor complications, mostly discomfort at the first web space between the toes.
- 33 of the 40 completed the study.
It had no comparison group, so it cannot prove the separator caused the improvement. A review in American Family Physician found no evidence that over-the-counter interdigital pads, a similar product, correct bunion deformities. The fair summary: a separator may ease pain and is low risk, but it is not a correction.
Types of separator
| Type | Where you wear it | Notes |
|---|---|---|
| Single wedge spacer | In shoes, all day | The slimmest option; can slip out without a loop |
| Single loop spacer | In shoes | A loop around the second toe holds it in place |
| Double loop spacer | In roomy shoes | More stable; slightly bulkier |
| Spacer with bunion shield | In roomy shoes | Adds a pad over the bump |
| Five-toe spreader | Barefoot, at rest | Spreads all toes; too bulky for most shoes |

How to choose and wear one
- Start small and soft. A spacer that is too thick forces the toes apart and is the usual cause of discomfort between them.
- Build up. Begin with an hour or two. The study participants wore theirs for 6 hours a day, which is a reasonable target if it stays comfortable.
- Make room in your shoes. AAOS advises a wide toe box that does not squeeze the toes and 3/8 to 1/2 inch of space for the longest toe. A separator adds width.
- Check your skin. Look for redness, blisters or soft corns between the toes after each use.
- Keep it clean. Wash silicone in warm soapy water and dry it fully before wearing again.
When a separator is not the answer
If your bunion is red, hot and swollen, get it checked before using a separator. The same goes for a stiff, painful big toe joint, which may be arthritis rather than a bunion. And if the bunion is on the little toe side, a big toe spacer will not help; see tailor's bunion correctors instead.
What to look for when you buy
Silicone single-loop big toe spacer
Best for: Daytime use in shoes for rubbing between the big and second toe
The loop holds the spacer in place, and the study above used a prefabricated silicone separator worn in shoes.
Watch out: Discomfort between the toes was the most common minor complication in that study.
See options on AmazonGel spacer with bunion shield
Best for: A bump that rubs on the shoe as well as crowded toes
Combines a spacer with a cushion over the bump, the two items AAOS lists as pads and spacers.
Watch out: Bulkier; needs a shoe with a wide toe box.
See options on AmazonFive-toe spreader for rest
Best for: Stretching the toes apart while sitting or relaxing barefoot
Spreads all toes at once for comfort when shoes are off.
Watch out: Too bulky for most shoes and not shown to correct a bunion.
See options on AmazonWide toe box shoes
Best for: Anyone wearing a separator during the day
AAOS recommends a wide or open toe box. Without it, the separator just adds pressure.
Watch out: Try them on with the separator in place.
See options on AmazonQuestions people ask
- Do toe separators fix bunions?
- No. They may ease pain and rubbing. A 12-month study found less pain and no worsening of the angle, but no straightening, and a medical review found no evidence that toe pads correct bunions.
- How long should I wear toe separators for bunions?
- Build up gradually. In the study, people wore them for 6 hours a day. Stop if they cause pain, numbness or skin irritation.
- Can I wear toe separators in shoes?
- Slim single or loop spacers fit in shoes with a wide toe box. Five-toe spreaders are for barefoot rest.
- Can I sleep with toe separators in?
- Some people do, but a small spacer can slip out at night. A night splint is the device designed for resting.
