Night Splints

A night splint is an orthopaedic support worn while resting or sleeping to keep the foot and ankle in a gently stretched position. It holds the foot at a right angle so the plantar fascia and calf muscles remain slightly stretched overnight. This helps prevent the tissues from tightening while you sleep, which is a common cause of sharp heel pain when taking the first steps in the morning.

Night splints are most commonly used for plantar fasciitis, a condition that causes inflammation of the band of tissue running along the bottom of the foot. By maintaining a consistent stretch during rest, a plantar fasciitis night splint may help reduce morning stiffness and allow the tissue to heal more gradually. Many people find that regular overnight use can improve comfort when getting out of bed and starting the day.

Night splints are often recommended for people experiencing persistent heel pain caused by plantar fasciitis or tightness in the Achilles tendon. These conditions can cause discomfort that is particularly noticeable first thing in the morning or after periods of rest. Wearing a night splint helps maintain a gentle stretch in the foot overnight, which may reduce the severity of this pain.

They may also be helpful for people with calf tightness, tendon inflammation or certain foot conditions where stretching the plantar fascia and Achilles tendon is beneficial. In many cases, night splints are used alongside other treatments such as stretching exercises, orthotic insoles or supportive footwear as part of a broader foot care plan.

Night splints are designed specifically for overnight use, but it can take some time to adjust to wearing one while sleeping. Many designs include padded liners, adjustable straps and lightweight frames to make them more comfortable during rest. Some styles also allow slight movement while still keeping the foot supported in the correct position.

It is common for people to begin by wearing the splint for shorter periods before using it throughout the night. Gradually increasing wear time can help the body adapt to the position of the splint. Choosing the correct size and adjusting the straps properly can also improve comfort and ensure the foot remains supported without causing pressure or irritation.

Night splints are typically worn during sleep or periods of extended rest, such as when lying down in the evening. The goal is to keep the foot in a gently stretched position for several hours so the plantar fascia and calf muscles do not tighten overnight. Many people wear a plantar fasciitis night splint throughout the night as part of their treatment routine.

The length of time a night splint is needed can vary depending on the severity of the condition and how quickly symptoms improve. Some people use them for several weeks as symptoms settle, while others may use them for longer periods alongside stretching and supportive footwear. Advice from a healthcare professional can help determine the most suitable duration of use.

Yes, although night splints are most commonly associated with plantar fasciitis treatment, they can also be used for other conditions affecting the foot and ankle. They may help with Achilles tendon tightness, certain calf muscle injuries or other problems where keeping the ankle gently stretched overnight is beneficial.

By maintaining a neutral ankle position during rest, the splint can help reduce muscle shortening and stiffness that develops when the foot remains pointed downward during sleep. This stretching effect may support recovery and improve flexibility in the lower leg, depending on the underlying condition.

Night splints should be cleaned regularly, especially if they are worn for long periods overnight. Most designs include removable padded liners or straps that can be hand washed using mild soap and warm water. Keeping these parts clean helps maintain hygiene and prevents the build-up of sweat or odours.

The rigid frame or outer shell can usually be wiped with a damp cloth and allowed to air dry. It is also a good idea to check the straps and fastenings occasionally to ensure they remain secure and in good condition. Proper care helps maintain comfort and ensures the night splint continues to provide effective support.
