How does compression work?
The primary function of compression socks is to promote the return of blood to the heart by compressing the leg veins. To be effective, the compression must be "degressive", i.e. stronger at the extremities of the limb, then weaker and weaker as we move up towards the body. The measurement compression level is in millimetres of mercury (mmhg). The lightest low supports have a compression of 15-20mmhg. While medical compression stockings have a higher compression, about 20-30mmhg and sometimes more. For this reason, it is important to consult an orthotist in order to be well advised.
