The SD Calf Support 2-pack is designed to provide compression and support to the calf muscles during physical activities such as running, hiking, and cycling. The support is made from a comfortable, breathable neoprene material that helps to retain body heat and increase blood flow to the muscles. The adjustable strap allows for a custom fit, while the open-toe design provides added comfort and support. The support can help to reduce muscle soreness, prevent injury, and promote faster recovery after physical activity. The pack includes two calf supports, making it easy to have a spare on hand or use both during high-intensity activities.
