Scientific studies show that regular use of a night splint helps treat plantar fasciitis. Cool Stretch delivers a dynamic combination of cold therapy to reduce inflammation and fixed angle support for effective passive stretching of the plantar fascia throughout the night. The rigid yet comfortable low-profile design provides constant 90-degree dorsiflexion of the foot, alleviating morning tension and stiffness. The sealed ice pack moves freely for targeted pain relief. Adjust the tension with two hook-and-loop straps.
