The Strassburg Sock night splint for plantar fasciitis — White Regular (fits calves up to 16") breathable overnight stretch

The Strassburg Sock is a comfortable, clinically proven night splint that holds your foot in a gentle stretch while you sleep to ease plantar fasciitis, heel pain, Achilles tendon tension and tight calves.

Designed for overnight wear, this white Regular-size sock reaches from the foot to just below the kneecap and keeps the ankle dorsiflexed to maintain a steady, therapeutic stretch through the plantar fascia and calf muscles. The Regular fits calf circumferences up to 16 inches; straps are adjustable so you can secure a steady, non-constricting hold. Built from a soft, breathable knit, the sock is intended for gradual adaptation—start with short sessions then increase to overnight as comfortable.

How does the Strassburg Sock reduce morning heel pain?

By keeping the foot gently pulled upward during rest, the sock prevents the plantar fascia from contracting into a shortened position overnight. This steady stretch helps lessen the sharp pain many people feel on first steps in the morning. It’s a mechanical approach—no medications—meant to complement other therapies like stretching or physical therapy.

• Maintains ankle dorsiflexion to reduce overnight tightening.
• Even, steady tension avoids sudden strain on the fascia at wake-up.
• Wear progression: begin 1–2 hours, then increase to all-night use as tolerated.

What size should I choose and how should it fit?

The Regular size accommodates calves up to 16 inches measured at the widest point just below the knee. Straps should be snug enough to keep the sock from slipping but not so tight they cut off circulation or create discomfort. If your measurement is close to 16 inches or you’re between sizes, choose the Large for a more comfortable, effective fit.

• Measure at the widest part of the calf, just below the kneecap.
• If measurement approaches 16", sizing up is recommended.
• Adjust straps gradually to find secure, non-restrictive tension.

How do I use and care for the sock for best results?

Begin by wearing the sock for short periods—1 to 2 hours—while relaxing to become accustomed to the stretch. Gradually increase wear time to overnight as tolerated. The knit fabric is made for nightly use and should be kept clean per care instructions; proper maintenance preserves fit and comfort.

• Start with short sessions, then progress to overnight wear.
• Keep straps snug but comfortable; avoid over-tightening.
• Follow washing guidelines to maintain material breathability and shape.

What materials and design features make it comfortable at night?

The Strassburg Sock uses a lightweight, breathable knit that rests softly against the skin and minimizes irritation during extended wear. Its length reaches below the kneecap, providing consistent stretch from the heel up through the calf without bulky splints. The adjustable strap system secures the position while allowing micro-adjustments to match personal comfort.

• Soft, breathable fabric for comfortable all-night wear.
• Length designed to maintain even stretch along the calf and plantar fascia.
• Adjustable straps for a tailored, secure hold without pinching.

Who is this for? The Strassburg Sock Regular is suited for adults experiencing plantar heel pain, Achilles tendon tightness, or recurring calf stiffness who want a non-invasive, mechanical method to reduce discomfort and support recovery during rest. It’s appropriate for people beginning a conservative treatment plan, those looking to complement stretching or therapy, and anyone preferring a soft, strap-secured night splint. If you’re close to the upper size limit, consider the Large for a more comfortable fit.
