Dorsiflexion Night Splint
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Wear a night splint that holds the ankle at roughly 90 degrees (or in slight dorsiflexion) while you sleep, every night for 1-3 months. Sock-style dorsal splints are more comfortable than rigid boot styles and improve compliance. Most useful for people whose worst pain is the first steps of the morning. Combine with daytime stretching.
How it works
Overnight, the foot naturally rests pointed downward, letting the plantar fascia and calf tighten and heal in a shortened position - which re-tears with the first morning steps. A splint keeps the fascia and Achilles under gentle sustained stretch all night, so healing occurs at functional length and morning pain drops. It effectively delivers an 8-hour low-load stretch.
Where to buy
Amazon, pharmacies, and medical supply stores - Vive Hard Plantar Fasciitis Night Splint, Cheeky Physio Sock Night Splint, and United Ortho brands are common.
Typical cost: $20-$40 one-time
Safety notes
Can disturb sleep and cause calf or forefoot discomfort at first - start with a few hours per night. People with diabetes, neuropathy, or circulation problems should check skin daily and consult a clinician before use. Do not strap so tightly that toes tingle or go numb.
