Best Plantar Fasciitis Night Splints
A plantar fasciitis night splint works by keeping your foot dorsiflexed while you sleep, so the fascia doesn't tighten overnight — which is exactly what causes that stabbing first-step pain. We wore a dorsal splint over 6 weeks and documented exactly how wearable it is in practice.

Frequently Asked Questions
Do plantar fasciitis night splints actually work?
The mechanism is sound: holding the foot dorsiflexed overnight stops the fascia tightening, which is what causes first-step morning pain. Compliance is the problem. In our 6-week test the dorsal splint caused constant mid-night awakenings and was abandoned most nights, and a splint you don't wear does nothing. Clinical evidence on long-term benefit is mixed for the same reason.
Dorsal vs boot night splint for plantar fasciitis?
We tested a dorsal (low-profile, front-of-shin) splint because boot-style splints are bulkier and even harder to sleep in. The dorsal design is the more wearable of the two and still disrupted sleep. If mornings are your worst symptom, try a dorsal splint first and expect an adjustment period.
What can I do about morning heel pain if I can't tolerate a night splint?
Before the first step, stretch the calf and roll the arch on a frozen bottle for 2-3 minutes while still sitting. A supportive slipper by the bed (we tested the Vionic Relax II) means your first weight-bearing step lands on arch support instead of a bare floor.
