Achilles and calf tightness doesn’t take a break overnight, so the NightSock works while you sleep — a patent-pending design holds the foot in a gentle semi-flexed position, with adjustable straps that let the stretch progress over time. A soft, breathable sock and low-profile hook-and-loop fasteners mean it won’t snag the sheets by morning.
Does the NightSock stretch the foot while you sleep? Yes — the NightSock is designed to hold the foot in a semi-flexed position overnight to stretch the Achilles, calf, and plantar fascia.
