KNOB-LOCK FOR ALL-NIGHT SECURITY — Tired of waking up at 3 AM to re-tighten loose hook-and-loop straps? Our double-hook precision knob creates a mechanical lock that holds your dorsiflexion angle through every toss and turn. Designed to stay secure through normal sleep movement, giving you uninterrupted rest and consistent stretch all night long. WAKE UP WITHOUT THAT FIRST-STEP AGONY — Morning heel pain from plantar fasciitis happens because your fascia contracts overnight. Supurelax holds your ankle at a gentle 15-degree dorsiflexion angle while you sleep, keeping the plantar fascia and Achilles tendon continuously elongated so tissues stay relaxed by the time your feet hit the floor. Ideal for runners, nurses, teachers, warehouse workers, and anyone whose day begins with that dreaded stabbing step.
PRECISION SPECS DESIGNED FOR REAL RELIEF — Weighing only 5.6 oz (160g), lighter than most smartphones, this splint uses high-density foam padding and breathable nylon fabric — no aluminum bars or hard plastic frames that create uncomfortable pressure points. The double-hook knob allows millimeter-level tension adjustment. Fits calf circumference 10–15 in (25–38 cm). Compatible with US Men's Size 4–9 / Women's 5–10 (max foot length 9.8 in / 25 cm). Left and right foot universal. Smooth ABS knob — comfortable fit for sensitive areas. BUILT FOR EVERY HEEL PAIN SUFFERER — Designed for plantar fasciitis, Achilles tendonitis, heel spurs, foot drop, flat feet, high arches, and post-surgical recovery. One size fits most adults — no left/right sorting required. A thoughtful recovery gift for marathon runners pushing through training season, retail workers on their feet all shift, pregnant women managing pregnancy-related heel pain, or any loved one dealing with chronic morning stiffness. Includes a frosted drawstring carry bag (27 x 15 cm) for travel and storage. With 3.9 stars on Amazon, it's earning solid feedback from real buyers — check recent reviews to see if it fits your needs.
