Mediven Sheer & Soft compression stockings are some of the sheerest stockings on the market today. The 20-30 mmHg firm compression helps with the prevention and relief of moderate to severe varicose veins and is typically the preferred level of compression following surgical treatments. Mediven Sheer & Soft compression stockings are available in 8-15 mmHg, 15-20 mmHg, and 30-40 mmHg. The higher the set of numbers the greater the compression or squeeze you will experience on your leg. Need help determining the appropriate compression level, click here to view our compression guide.
