Description
What Is a Plantar Fasciitis Night Splint?
A plantar fasciitis night splint is a brace worn in bed that holds the foot in dorsiflexion, so the plantar fascia and the Achilles tendon stay under a gentle, sustained stretch while you sleep instead of tightening up overnight. Model AN-006 is a three-size overnight splint. The manufacturer states its support function as nighttime foot immobilisation and dorsiflexion support, and lists plantar fasciitis, Achilles tendon support and foot drop positioning as its applications. It is an overnight device, not a daytime ankle support, and it is not a walking boot.
Why Choose This 3-Size Overnight Splint?
Stays put. So you can forget it’s there. The reason people abandon a night splint is almost never the stretch — it is that the brace is uncomfortable at two in the morning, or that it moves because it does not match the leg it is on.
A plantar fasciitis night splint that is offered in separate sizes for the foot rather than a single adjustable shell keeps the same geometry at every size, so the heel stays seated and the toes stay lifted instead of the brace riding up the calf. The three sets of measurements below are what you are choosing between: small, medium and large each have their own unit length, width and weight rather than one shell stretched to fit everyone.
- Three separate sizes: S, M and L each carry their own unit dimensions and weight, so a plantar fasciitis night splint keeps its shape instead of being oversized on a smaller foot.
- Nighttime foot immobilisation: The stated support function of this model, so the position you set at bedtime is the position your foot is still in at 3 a.m.
- Dorsiflexion support: The foot is held with the toes lifted rather than dropped, which is the position the plantar fascia needs overnight.
- Adjustable fit: Hook-and-loop fastening lets the tension be reset without taking the splint fully off.
- Sponge padding: Padding sits between the shell and the skin, which is what makes an eight-hour session realistic.
- Either foot: The same splint fits the left and the right foot.
Premium Engineering & Design Details
Every value below applies to model AN-006, the plantar fasciitis night splint in this listing.
Night-Time Immobilisation & Dorsiflexion Support
Two phrases describe how this plantar fasciitis night splint works, and both come from the manufacturer’s own field sheet: nighttime foot immobilisation, and dorsiflexion support. Immobilisation means the foot is not free to drop back into the pointed position most people sleep in; dorsiflexion support means it is held with the toes lifted instead. Put together, the splint replaces the position your foot would otherwise spend the night in with the position the plantar fascia needs — a stretch that is gentle enough to sleep through precisely because it lasts for hours rather than being forced.
That is also why this one is a sized splint rather than a one-size shell. A plantar fasciitis night splint only holds a position if it stays where it was placed, and it only stays where it was placed if the body of the splint matches the length of the foot and the shape of the calf.
The three sizes exist so that the geometry of the stretch is the same whether the splint is fitted on a small foot or a large one. The manufacturer’s page for this model presents its specifications as a table rather than a separate feature list, so everything above is described exactly as that page states it.
Best For: Plantar Fasciitis, Achilles Support & Foot Drop Positioning
This plantar fasciitis night splint is intended for the situations below, quoted from the manufacturer’s application field for this model.
- Plantar fasciitis, as stated on the manufacturer’s page
- Achilles tendon support, as stated on the manufacturer’s page
- Foot drop positioning, as stated on the manufacturer’s page
- Morning heel pain and first-step stiffness that eases as the day goes on
- An overnight stretch prescribed alongside a daytime stretching and strengthening routine
The American Academy of Orthopaedic Surgeons explains why the overnight position matters: most people sleep with the feet pointed down, which lets the plantar fascia relax and tighten, and a night splint holds the foot in a stretched position so the tissue does not contract back overnight.
See the AAOS patient information on plantar fasciitis and bone spurs for how that mechanism is described and what the first-line treatments are. One limit belongs in plain language: this plantar fasciitis night splint positions and stretches the foot, and it does not treat the cause of the pain on its own — that is why it is usually one part of a programme that also includes daytime stretching.
Sizing & Fitting Guide (S · M · L)
Three sizes, each with its own unit measurements and weight. Because this plantar fasciitis night splint is bought for a foot rather than for a shoe, the measurement that matters is the length of the foot from heel to the base of the toes, checked against the length of the splint rather than against a shoe size.
Loosen the fastening fully, seat the heel at the back of the plantar fasciitis night splint, then close the strap so the foot is held without pressure points over the top of the foot. If you wake with numbness or pins and needles, the fastening is too tight.
One practical point for choosing: if the foot measurement sits between two sizes, take the larger one and use the fastening to take up the slack. A plantar fasciitis night splint that is too small will not settle onto the heel, and it will end up back in the cupboard.
Who It’s For — and Who It Isn’t
This plantar fasciitis night splint suits the foot that needs to be held in a stretched position overnight.
- A good match when heel pain is worst at the first step in the morning and eases after a few minutes of walking.
- A good match when a clinician has already started a stretching and strengthening programme and wants the overnight position controlled as well.
- A good match when a single-size adjustable splint has felt loose, or when a plantar fasciitis night splint in the wrong size has moved during the night.
- Not the right choice when the ankle has to be immobilised after a fracture or a repair, or when weight bearing has to be controlled — an overnight splint is not a walking device.
- Not the right choice for broken skin, poor circulation or a nerve problem in the foot, where pressure from any splint needs medical advice first. Browse the full ankle and foot braces range for daytime options.
Frequently Asked Questions (FAQ)
Do I wear it on bare skin or over a sock? A thin, seam-free sock is usually the comfortable option, because it keeps the padding from rubbing and lets you check the skin underneath. Whichever you choose, check the top of the foot and the heel after the first few nights.
How many hours should I wear it? That is a clinical decision and depends on your injury. The common pattern is to build up gradually over the first nights rather than going straight to a full night, but the schedule should come from your clinician.
Can I walk in it? No. This plantar fasciitis night splint is designed for the bed. Walking in a night splint is unsafe, and if you need a walking device you need a boot rather than a splint.
Do I still need a daytime plantar fasciitis brace? They do different jobs. A plantar fasciitis night splint holds the stretch while you sleep; daytime support and stretching address the load during the day. Many programmes use both, which is why the two are usually prescribed together rather than instead of each other.
Which size should I choose? Measure from the back of the heel to the base of the toes and compare against the unit lengths in the sizing table. If you are between two sizes, take the larger one.
How do I clean it? Hand-wash the padded parts in cool water with a mild soap, rinse well and air-dry away from direct heat. Close the hook-and-loop fastening before washing so it does not catch on the padding.
