Night splints for plantar fasciitis: do they work, and which to buy

Short answer
Yes, for the right person. The 2023 physical-therapy guideline gives night splints a strong (Grade A) recommendation for people whose heel pain is worst with the first steps in the morning, used for one to three months. A splint holds your ankle near 90° overnight so the plantar fascia and calf don't tighten. The Vive boot-style splint is the most adjustable; the Strassburg Sock is lighter if you can't sleep in a boot.

Vive Plantar Fasciitis Night Splint

- 3 adjustable straps
- Left or right foot
- 60-day guarantee
Skip it if: you're a restless sleeper who hates rigid braces.

Illustration Best soft alternative
The Strassburg Sock
A soft sock with a strap from the toes to below the knee that keeps the foot gently flexed. Lighter and cooler than a boot, but the stretch depends on how you set the strap.
- Soft knee-high sock
- Strap pulls toes up
- Regular fits calves up to 15"
- Large size for bigger calves
Skip it if: you want a precise, repeatable angle; boots are more consistent.

How to use a night splint
- Start with a gentle angle; it should feel like a mild stretch, not pain.
- Wear it for a few hours, then build up to the whole night.
- Keep it up for one to three months, alongside daily stretching.
- Stop and see a clinician if you get numbness, tingling or skin irritation.
Common questions
Can I walk in a night splint?
Most aren't made for walking. Take it off before getting up, then put on supportive slippers.
