Travel socks are specially designed to prevent economy class syndrome, which can occur during airplane travel or long car or train journeys. The tapered compression they provide from the ankle to the knee helps improve blood circulation and facilitates venous return from the feet to the heart. With Medilast travel socks, you'll arrive at your destination with less tired legs and less ankle swelling. Travel socks are a preventive class garment for tired legs, with tapered compression from 15 to 21 mmHg (Class I). They apply gentle pressure starting at the ankle and facilitate venous return of blood to the heart. This helps prevent circulation problems such as varicose veins, spider veins, tired legs, or tingling. Wearing compression garments while traveling will help improve leg circulation and also provide a pleasant feeling of rested legs upon arrival at your destination.
