Night splints may be used to treat plantar fasciitis. The splint holds the foot with the toes pointed up and with the foot and ankle at a 90-degree angle. This position applies a constant, gentle stretch to the plantar fascia. It also stretches the Achilles tendon at the back of the heel, preventing it from contracting. You can wear night splints every night for up to several months. Then you can gradually reduce how often you use them as your symptoms go away.

You can continue other treatment with nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, or orthotic devices while you use night splints.

Night splints may be helpful for some people with long-lasting (chronic) plantar fasciitis.
