Description
What Is a Dorsal Night Splint?
A dorsal night splint is a padded brace worn in bed that holds the foot in dorsiflexion, so the plantar fascia and the Achilles tendon are kept under a gentle, sustained stretch instead of tightening overnight. “Dorsal” describes where the shell sits: over the top of the foot and shin rather than under the sole. Model AN-001 is a prefabricated dorsal night splint with soft foam padding, a heel-lock strapping system and an adjustable dorsiflexion strap. It is not a daytime ankle brace, and it is not a walking boot.
Why Choose This Overnight Splint?
Stays put. So you can forget it’s there. That matters more for a dorsal night splint than for almost any other brace, because it is worn for seven or eight hours while you are asleep: if it digs in or works loose at two in the morning, the treatment stops and the brace gets pushed off. Two decisions in this model go at that problem — soft foam padding rather than a hard shell against the skin, and a heel-lock strap that anchors the foot instead of relying on tension alone.
- Prefabricated shell: The splint arrives as a formed unit rather than a flat piece to be shaped, so the angle is set by the structure instead of by how tightly it is strapped.
- Heel-lock strapping system: The heel is anchored first, which is what stops the foot from creeping down inside a dorsal night splint overnight.
- Adjustable dorsiflexion strap: The strap sets how much stretch the foot is held under, so it can be eased back if the calf feels tight in the first nights.
- Fits the right or left foot: One dorsal night splint covers either side, so there is no left or right version to order.
Premium Engineering & Design Details
Every value below applies to model AN-001, the dorsal night splint in this listing.
Heel-Lock Strapping & Dorsiflexion Strap
Two straps do different jobs on this dorsal night splint, and understanding the order makes it far easier to sleep in. The heel-lock system goes on first: it seats the heel at the back of the shell so the foot cannot slide down during the night. The dorsiflexion strap goes on second and sets how much stretch the foot is held under — it is the strap that decides whether the calf feels gently lengthened or uncomfortably tight.
Start with less stretch than you think you need, then tighten the dorsiflexion strap a little every few nights as the calf accepts it. If the foot goes numb, tingles or turns cold, the strap is too tight: loosen it and re-check the heel position. The padding is there to make long wear bearable, but a dorsal night splint only works while it stays on, so the aim is the least tension that still produces a stretch rather than the maximum the strap will allow.
Best For: Plantar Fasciitis & Achilles Recovery
This dorsal night splint is intended for the clinical situations below, taken from the manufacturer’s product information. Final suitability is a clinical decision, and the splint is supplied for use under medical guidance.
- Plantar fasciitis
- Achilles tendon repair and recovery
- Foot drop positioning, where the foot needs to be held rather than left to fall
- Post-static pain — the stiffness felt after a period of rest
- Anyone whose clinician has asked for a sustained overnight dorsiflexion stretch rather than a daytime support
- Use as a positioning aid during rest, in place of an unstructured sock or pillow under the foot
The reasoning behind night-time splinting is set out by the American Academy of Orthopaedic Surgeons, which explains that most people sleep with their feet pointed down, that this relaxes the plantar fascia, and that a night splint stretches the plantar fascia while you sleep — adding that although it can take getting used to, a night splint is very effective at reducing heel pain from plantar fasciitis.
See the AAOS patient information on plantar fasciitis and bone spurs for how the condition is assessed and treated. One limit belongs in plain language here: a dorsal night splint holds the foot in position and provides a sustained stretch overnight. It works alongside stretching and loading changes rather than replacing them, and whether it belongs in your plan is a clinical decision rather than a product feature.
Sizing & Fitting Guide (S/M · L/XL)
This dorsal night splint is made in two size ranges rather than individual sizes, and it fits either foot. Choose the range from your measured foot length and confirm it with your clinician; the measured dimensions and unit weight of each range are listed below.
Measure from the heel to the tip of the longest toe and compare it with the internal length of the range you are considering. Then fasten the heel lock first, add the dorsiflexion strap second, and set the stretch low for the first nights.
Two practical notes. Both ranges ship in the same 57 × 36 × 42 cm carton, with 30 pieces per carton for S/M and 27 for L/XL — worth knowing if you are ordering for a clinic rather than for one patient. And a dorsal night splint is usually worn for weeks rather than days, so check the straps and the padding at each follow-up: the padding is what makes it tolerable, and it is also the part that wears first.
Who It’s For — and Who It Isn’t
This dorsal night splint suits the patient who has been asked to stretch the calf and plantar fascia overnight, and who needs something that can stay on until morning.
- A good match when the clinician has prescribed a sustained overnight dorsiflexion stretch for plantar fasciitis, Achilles recovery or post-static pain.
- A good match when a daytime brace has already been tried and the problem is the morning stiffness rather than daytime support.
- A good match when the foot needs to be held in position overnight, including foot drop positioning where the foot would otherwise drop.
- Not the right choice when the foot needs to be immobilised for a fracture, or when weight bearing has to be controlled — a dorsal night splint is a night-time positioning device, not a walking brace.
- Not the right choice for walking or daytime activity, or as a substitute for the strengthening work in your rehabilitation plan. Browse the full ankle and foot braces range if you need support you can wear during the day.
Frequently Asked Questions (FAQ)
Can I really sleep in it? That is what it is designed for, and the soft foam padding exists to make a full night tolerable. Most people do best by starting with less dorsiflexion stretch and building up over the first week rather than setting it tight from night one.
Should I wear a sock underneath? A thin, smooth sock usually reduces rubbing and helps the foam padding sit evenly against the skin. Avoid anything with seams or heavy texture under the straps.
Which foot does it fit? Either. This dorsal night splint is not made in left and right versions, so the same unit fits both feet.
How does the heel-lock strap differ from the dorsiflexion strap? The heel lock seats the heel at the back of the shell so the foot cannot slide down during the night; the dorsiflexion strap then sets how much stretch the foot is held under. Fasten them in that order.
How tight should the dorsiflexion strap be? Tight enough to keep a gentle stretch on the calf, not tight enough to cause numbness, tingling or a cold foot. If any of those appear, loosen the strap and re-check the heel position.
How long will I need it? That depends on your condition and is set by your clinician. A dorsal night splint is generally worn for weeks rather than days, so treat the padding and straps as parts that need checking along the way rather than as a one-off purchase.
