Description
Quick answer: This is the Össur Airform dorsal night splint — a lightweight, low-profile foot/ankle splint worn at night to relieve plantar fasciitis and Achilles tendonitis pain. It holds the foot at a right angle (neutral dorsiflexion) so the plantar fascia and Achilles tendon get a gentle, sustained stretch overnight, helping reduce the sharp morning heel pain and stiffness. Its dorsal (front-of-shin) design is smaller and lighter than most night splints, so it’s more comfortable to sleep in — which means people actually keep it on. Slip-on with adjustable straps; fits either the left or right foot. No prescription required for purchase.
What’s included
- 1 × Össur Airform dorsal night splint (in your selected size)
About this product
Plantar fasciitis pain is often worst first thing in the morning — because the plantar fascia tightens overnight, then stretches painfully with your first steps. A night splint addresses this by keeping the foot gently stretched while you sleep:
- Holds the foot at 90° — a neutral, right-angle position that keeps the Achilles tendon and plantar fascia in a lengthened state overnight (static-progressive stretch/rehabilitation).
- Reduces morning pain — that sustained stretch means less sharp heel pain and stiffness with your first steps.
- Dorsal, low-profile design — the splint sits along the front of the shin/foot (not a bulky posterior boot), so it’s smaller and lighter than most night splints — more comfortable to wear, which improves compliance.
- Easy to use — slips on and adjusts easily with hook-and-loop straps; fits either the left or right foot.
- For multiple conditions — plantar fasciitis, heel spurs, Achilles tendonitis (tendinosis), Achilles strains/bursitis, drop foot, tight calves, and post-static foot pain.
Sizing
Comes in two sizes based on typical men’s/women’s shoe size (confirm the size chart for your shoe size). The splint fits either foot, and accommodates a range of foot sizes within each size.

Frequently asked questions
How does a night splint help plantar fasciitis?
It holds your foot at a right angle overnight, keeping the plantar fascia and Achilles tendon gently stretched — so they don’t tighten up while you sleep, which reduces the sharp heel pain and stiffness you feel with your first morning steps.
Why the dorsal design?
The dorsal (front-of-shin) style is smaller and lighter than bulky posterior boot splints, so it’s more comfortable to sleep in — and people are more likely to actually wear it all night.
Which foot does it fit?
Either — it fits the left or right foot. Choose your size based on the men’s/women’s shoe-size chart.
What conditions is it used for?
Plantar fasciitis, heel spurs, Achilles tendonitis, drop foot, tight calves, and post-static foot pain.
Is it the same as the Össur Formfit night splint?
No — the Airform is the dorsal style. The Formfit is a different (posterior) model with adjustable dorsiflexion. Both treat similar conditions.
Do I need a prescription?
No prescription is needed to purchase. If you have a specific medical condition, check with your provider on suitability.
Can I get it delivered in Brooklyn or shipped nationwide?
Yes — Stark Medical Supplies offers local pickup and delivery in Brooklyn and across NYC, plus USPS shipping throughout the continental U.S.
