Wake up without that stabbing first-step pain. The OPTEC USA Night Splint is an adjustable dorsiflexion boot that gently holds your foot and ankle in a stretched position overnight — keeping the plantar fascia and Achilles tendon lengthened while your body rests, so that first morning step hurts less. Unlike buckle-style splints, ours closes with soft, tool-free Velcro straps. Set your stretch and snugness one-handed in seconds, even in the dark — no clips to fumble or pinch, and easy to fine-tune as your comfort changes. A lightweight shell, breathable cushioned liner, and padded calf and ankle straps keep it comfortable enough to wear all night without disrupting your sleep. Designed primarily for plantar fasciitis. It may also help with Achilles tendonitis and general overnight foot-and-calf stretching — if you're treating Achilles specifically, check with your doctor on the right wear schedule, since positioning needs can differ. Best used for resting and sleeping. The non-skid base makes an occasional step to the bathroom safer, but this is a night splint, not a walking boot — avoid walking around in it.
