HealWell Plantar Fasciitis Night Splint - Clinical Stretch Orthosis
The HealWell Night Splint by Essity Medical Solutions is a professional-grade orthosis engineered to treat Plantar Fasciitis, Achilles Tendonitis, and other lower-extremity overuse injuries. By maintaining the foot in a consistent dorsiflexed position during sleep, this splint provides a sustained "Zero-Friction" stretch to the plantar fascia and calf muscles, preventing the nighttime contraction that leads to acute morning pain.
Nationwide Shipping & Regional Expertise
Medical Department Store is an authorized provider of Essity Medical Solutions. While we offer rapid nationwide shipping, our local showrooms—serving Sarasota, Naples, and Fort Myers—ensure every splint is vetted for the breathability and comfort required in warm coastal climates. The foam-laminate liner is specifically designed to manage heat and moisture for all-night wear in the Southwest Florida humidity.
Key Features & Benefits
- Adjustable Dorsiflexion Straps: Dual-tension straps allow the user to gradually increase the angle of the stretch, accommodating the patient's flexibility as recovery progresses.
- Rigid Posterior Shell: Provides a stable foundation that prevents the foot from dropping into plantarflexion (pointing down) during the night, ensuring the fascia remains elongated.
- Breathable Padded Liner: The soft, moisture-wicking interface protects the skin and prevents irritation, making it comfortable for all-night use.
- Non-Slip Sole: Features a safety-tread bottom for limited, essential transfers (such as walking from the bed to the bathroom).
Clinical Authority: Preventing the "First-Step" Pain
The HealWell Night Splint is clinically indicated for Plantar Fasciitis and Achilles Tendonitis. The mechanical advantage lies in its ability to prevent the plantar fascia from healing in a shortened, contracted state overnight. By facilitating a continuous low-load stretch, the splint reduces the micro-tearing that occurs when taking those first steps in the morning, accelerating the healing process for patients in the Naples and Sarasota medical communities.
Top Industry Applications
- Chronic Foot Pain Management: The gold standard for patients who have not found relief through daytime inserts or stretching alone.
- Active Retirees: Provides the recovery support needed to return to golfing, tennis, and walking in Southwest Florida.
- Post-Surgical Recovery: Used as a resting splint to prevent foot drop and maintain tendon length during rehabilitative phases.

Clinical FAQ
How tight should the straps be? You should feel a gentle, firm stretch, not pain. Start with a neutral angle (90 degrees) and gradually tighten the side straps over several nights.
Can I walk in this splint? The splint is designed for sleeping. While it has a non-slip sole for short trips to the bathroom, it is not intended for regular walking or weight-bearing exercise.
How do I clean the liner? The soft liner can be hand-washed with mild soap and air-dried. Ensure it is completely dry before re-attaching to the shell.
