The Falke Family Kids Socks are made of the high-quality and durable Supreme Green Cotton?. In the process of extracting this special cotton from Greece, as much as 40% less water is used and 20% of the energy comes from renewable sources. For example, Falke has managed to save an amount of CO2 for 1 kg of cotton that is normally emitted during a 15 km car journey. In addition, the socks sit comfortably on the feet due to the optimal support that the reinforced load zones offer you.
