United Ortho Plantar Fasciitis Night Splint Large - Ambidextrous, Adjustable 10–90° Dorsiflexion, Padded Black

The United Ortho plantar fasciitis adjustable leg support is a padded night splint that holds your foot in a controlled dorsiflexed position to maintain a gentle stretch of the plantar fascia and Achilles tendon while you rest.

This practical night splint combines an adjustable heel-to-calf frame, cushioned cool-foam lining, and non-skid tread so you can keep it on for limited walking around the home. Built by United Ortho (formerly United Surgical), the device is designed to fit either foot, fasten securely with wide straps, and allow precise adjustment from 10 to 90 degrees of dorsiflexion. The large size fits most adult feet and is made to be comfortable overnight with padded calf and ankle straps that minimize pressure points.

How does this brace apply a therapeutic stretch without waking you up?

The splint uses a rigid but lightweight frame and flexion straps to hold the foot at a chosen angle, providing a steady stretch without repeated movement. Padding at the calf and ankle reduces rubbing and the cool-foam liner helps manage temperature for overnight wear. The non-skid sole allows safe, limited ambulation if you need to get up briefly.

• Adjustable dorsiflexion range: 10–90 degrees for personalized stretching
• Flexion straps deliver controlled tension to the plantar fascia and Achilles
• Cool-foam liner and padded straps for pressure relief
• Non-skid tread for safe, short trips around the house

Will this splint fit my foot and can it be used on either side?

The device is ambidextrous, so the same splint fits the right or left foot, simplifying storage and replacement. The large size is intended for men’s 9.5–11.5 and women’s 10–12.5, but you should measure your foot to confirm the best fit. Wide hook-and-loop straps allow you to fine-tune fit around the ankle and calf for a secure, comfortable hold.

• Ambidextrous design: use on right or left foot
• Large sizing guideline: men 9.5–11.5, women 10–12.5
• Wide adjustable straps for secure, customized fit

What materials and comfort features make it wearable overnight?

United Ortho combined a firm external shell with a cool foam inner liner to balance support and comfort. Padded calf and ankle straps cushion pressure points, while breathable liner materials help keep skin drier during prolonged use. The non-skid sole reduces slipping during brief standing or walking, removing the need to take the splint off for short trips.

• Cool-foam liner for temperature control and cushioning
• Padded calf and ankle straps to reduce irritation
• Durable outer frame for consistent positioning night after night
• Non-skid sole for added safety during limited ambulation
