Aircast Dorsal Night Splint for Plantar Fasciitis, SM/MD and LG/XL

The Aircast Dorsal Night Splint holds the foot in a dorsiflexed position during sleep to gently stretch the plantar fascia and Achilles tendon overnight, helping to reduce the morning heel pain that is the hallmark symptom of plantar fasciitis. The dorsal (top-of-foot) design is lower profile and more comfortable than traditional posterior night splints, improving compliance for patients who struggle to sleep in bulkier devices. The flexible hinge allows optimal dorsiflexion adjustment for a customized stretch, while the soft, pliable softgood construction and removable, washable cloth liner keep the brace comfortable for extended nightly wear. An optional toe assist strap secures the toes within the forefoot area for additional stretch. Fits left or right foot. Available in SM/MD and LG/XL.

Indications

Ideal For

Patients with plantar fasciitis who experience sharp heel pain with their first steps in the morning — a classic symptom caused by the plantar fascia tightening overnight — will find that consistent use of this night splint helps maintain a gentle stretch through the night, reducing that initial pain upon waking. Individuals who have tried posterior night splints and found them too bulky or uncomfortable to sleep in will appreciate the dorsal design, which sits on top of the foot rather than behind the heel and is significantly less intrusive during sleep. Athletes and active adults managing chronic plantar fasciitis alongside a physical therapy program can use this splint as a passive overnight complement to their daytime stretching and strengthening exercises. People with Achilles tendon tightness or insertional Achilles tendinopathy who have been prescribed overnight dorsiflexion stretching by their podiatrist or orthopedic provider will find the adjustable hinge allows precise control over the stretch angle. Patients who have difficulty maintaining a consistent stretching routine during the day will benefit from the passive, hands-free nature of overnight splinting, which delivers a sustained stretch without requiring active effort.

Frequently Asked Questions

How does a dorsal night splint differ from a posterior night splint?
A posterior night splint wraps around the back of the calf and heel, which many patients find bulky and uncomfortable during sleep. A dorsal night splint sits on top of the foot and shin, holding the foot in dorsiflexion with a lower profile that is generally more tolerable for sleeping. Both achieve the same therapeutic goal of maintaining a passive plantar fascia stretch overnight.

How do I choose between SM/MD and LG/XL?
SM/MD fits Men’s shoe sizes 5–9.5 and Women’s 6–10.5. LG/XL fits Men’s shoe size 10 and above and Women’s 11 and above. If you are between sizes, consult your healthcare provider for guidance on which size will provide the most effective stretch angle for your foot.

What is the toe assist strap and do I need to use it?
The optional toe assist strap secures the toes within the forefoot section of the splint to add a gentle additional stretch to the plantar fascia. It is not required for basic use but may be recommended by your provider for a more aggressive stretch. Follow your healthcare provider’s instructions on whether and how to use this strap.

How do I clean the liner?
The cloth liner is removable — detach it from the splint and hand wash or machine wash on a gentle cycle with mild detergent. Allow to air dry completely before reattaching and wearing. Clean the hard shell with a damp cloth and mild soap as needed.
