DirectionsScholl Flight Socks should be worn in place of normal socks throughout the journey. Always wear both socks and ensure that they are pulled up to just below the knee. See enclosed leaflet for correct fitting and care. It is important that the socks are properly fitted. If they feel too loose or restrictive such that it causes pain or discomfort during application or in use, discontinue use and consult a healthcare professional for guidance. Please keep packaging and leaflet for future reference. Wash at 40oC (warm wash). Do not iron. USAGE ADVICE Normal ankle and calf sizes fit within these ranges. If you believe your ankle or calf size may fall outside these ranges or if the product feels too loose or restrictive such that it causes pain or discomfort during application or in use, discontinue use and consult a Healthcare Professional for guidance. To ensure correct fitting, Scholl recommends you measure your calf and ankle at the points indicated on the diagram prior to traveling.
