Night Splints

Night splints help keep the plantar fascia gently stretched while you sleep, which can reduce one of the common causes of morning heel pain caused by sleeping with the feet pointed down.

There are several styles of plantar fasciitis night splints available, including tension-based, rigid and dorsal designs. All can be effective, but personal preference plays a big part. Some people find rigid devices difficult to sleep with, while tension-based styles can feel a little too aggressive.

All our plantar fasciitis night splints are NHS quality and available to clinicians through NHS Supply Chain.

Night Splints

Night Splints for people with Plantar Fasciitis and Achilles Tendinitis 

Night splints are orthopaedic devices worn during sleep to help keep the foot in a gently dorsiflexed position.

For people with plantar fasciitis, Achilles tendon pain, or marked calf tightness, that overnight stretch can reduce the painful 'first few steps' in the morning and support a more consistent recovery plan.

This guide explains what night splints do, who they may suit, how different designs compare, and how to choose a practical option.

At a glance

Best known for: reducing morning heel pain linked to plantar fasciitis.
How they work: they help stop the foot dropping into a pointed position overnight.
Who may benefit: people with plantar fascia tightness, Achilles tendon discomfort, or post-static pain after rest.

Clinical note: night splints are generally used as part of a wider plan rather than as a stand-alone fix. If pain is severe, worsening or linked to swelling, numbness, trauma - seek professional assessment.

What is a night splint?

A night splint is a support worn on the foot and lower leg while you sleep. Its job is simple: to hold the ankle in a more neutral or slightly upward position, so the plantar fascia, Achilles tendon and calf tissues are not allowed to shorten fully overnight.

That matters because many people with plantar heel pain feel worst when they get out of bed. Overnight tightening can make the first stretch under body weight feel sharp and uncomfortable. A splint aims to reduce that sudden pull by maintaining a mild, sustained stretch while you rest.

Within the Algeos range, you will find low-profile options, adjustable designs, and more traditional boot-style splints in the wider braces and supports section.

Why people choose one

  • To reduce the painful first steps associated with plantar fasciitis.
  • To support overnight stretching of the Achilles tendon and calf complex in cases linked to Achilles tendonitis.
  • To introduce a passive treatment option that works while sleeping.
  • To improve tolerance of walking after rest or inactivity.
  • To combine with supportive insoles, massage tools, heel lifts, and stretching routines.
  • To build a more structured home care plan without relying only on daytime stretches.

How they help during sleep

1. Keeps tissues from shortening

During sleep, the foot often falls into plantarflexion. A splint helps keep the ankle closer to neutral so the plantar fascia and Achilles tendon remain under a gentle stretch rather than tightening fully.

2. Supports gradual recovery

By limiting overnight tightening, the tissues are exposed to less sudden strain on standing. This can make the morning transition to weight-bearing more manageable.

3. Encourages consistency

For people who struggle to keep up with regular evening stretching, a splint provides passive overnight positioning. Consistency often matters more than intensity.

Types of splints and who they may suit

Low profile

Night Splint with Heel Support

Night Splint with Heel Support

Useful for people who want a less bulky feel in bed and a comfort-first approach. A sensible starting point if tolerance is your main concern.

Adjustable angle

Padded Night Splint

Bodytonix Adjustable Plantar Fasciitis Night Splint

Designed for progressive stretching. Often suited to people who want more control over positioning and symptom progression.

Boot style

Darco Night Splint

DARCO Night Splint

A more traditional, supportive style that may suit people who do not mind a larger brace and want a classic night splint format.

Bundle option

Kit

Plantar Fasciitis Kit

Combines a night splint with a massage ball, making it easier to build a simple evening and daytime self-management routine.

You may also want to compare them with the Bodytonix Achilles Tendinitis Splint - Dorsal Design or the Bodytonix 90° Plantar Fasciitis Night Splint if you prefer a more specific fit or use-case.

Condition and use-case guide

Concern How a night splint may help
Plantar fasciitis with sharp morning heel pain Helps stop the plantar fascia tightening overnight, which may reduce pain on first standing.
Achilles tendon stiffness after rest Maintains a gentle stretch through the calf-Achilles unit and can support overnight positioning.
Persistent calf tightness affecting ankle movement Supports prolonged low-load stretching while sleeping, especially when combined with mobility work.
Heel pain needing daytime support too Night splints are often paired with insoles, heel cups, heel lifts, and footwear changes during the day.
People who dislike bulky braces A lower-profile or dorsal style may improve sleep tolerance and therefore consistency.

How to choose the splint

1

Start with the symptom pattern

If your main issue is plantar heel pain on the first steps of the day, a night splint may be worth considering. If pain is more activity-related, also review plantar fasciitis treatment options.

2

Choose a design you will actually wear

A highly supportive splint is no help if it stays in the cupboard. New users often start with a lower-profile option from the night splints collection.

3

Think about adjustability

If tissues feel very tight, a splint with more adjustment may help you build tolerance gradually rather than forcing an aggressive angle on night one.

4

Plan the daytime support too

Night-time positioning often works better alongside supportive orthotic insoles, Achilles heel lifts, and footwear with sensible structure.

5

Use it consistently, not aggressively

A mild, regular stretch is usually more practical than trying to force a strong correction. Build usage gradually and stop if symptoms worsen significantly.

6

Know when to get help

If pain is severe, persists despite treatment, or the diagnosis is unclear, speak to a suitably qualified clinician. Related support can also be found in the ankle braces and supports section and the wider AFO range when different support is required.

Frequently asked questions

Do night splints work for plantar fasciitis?

They can be useful for people whose symptoms are strongly linked to morning pain and overnight tightness. They tend to work best when used consistently and combined with supportive daytime measures such as insoles, stretching, and sensible load management.

Can a night splint help Achilles tendonitis too?

In some cases, yes. A splint may help maintain a gentle stretch overnight where calf and Achilles tightness are part of the problem. It is still important to look at overall management through the Achilles tendonitis section and related exercise advice.

Which style is easiest to sleep in?

That varies, but lower-profile or dorsal designs are often preferred by people who dislike bulky braces. A more traditional boot style may feel more supportive, though not always more comfortable.

Should I wear a night splint every night?

Many people build up gradually rather than starting with all-night wear straight away. Follow product guidance and professional advice, especially if symptoms are severe or you have other health considerations.

Are night splints enough on their own?

Usually they are one part of a broader plan. Daytime support, activity modification, footwear, and exercises often matter just as much as overnight positioning.

What else can I use with a night splint?
