The light compression ranges (less than 20 mm Hg) are preventative and can be worn by anyone wanting healthy, great-feeling and looking legs. Today incredibly sheer, lightweight and fashionable products are available in the lower compressions.

Frequent air travelers are just one potentially at-risk group, especially those passengers on long flights in coach class seating. Many ladies socks and hosiery are now available to accommodate this group.
