Heavy legs or vein problems? Especially on hot days or when standing for long periods, blood vessels expand and the blood does not circulate properly. Help your legs in winter and especially in summer. Compression of the leg veins supports the venous valves. BAHNER offers knee socks from 20den to 140den, hold-up support stockings, support stockings for suspenders, sports stockings and support tights in different compression levels and modern colors.
