Compression Levels

Compression stockings come in a variety of support levels to address different needs.

The levels are expressed in millimeters of mercury (mmHG) and in numerical ranges.

The higher the number, the stronger the support level, this means it will be firmer and the compression is tighter. The higher level of compression is for people with more advanced venous or leg conditions. Those will need to seek advice from their doctors on which level of compression would best suit them.
