Functional sock

A system providing targeted compression to portions of a lower extremity to provide improved venous return characteristics, the system comprising:

• one or more articles of clothing comprising:
• a first compression zone comprising a first proximal end and a second proximal end that are each disposed at anterior locations on a superior portion of the one or more articles of clothing,
• wherein the one or more articles of clothing are configured such, that when a user wears the one or more articles of clothing on the lower extremity with the anterior locations of the one or more articles of clothing covering an anterior portion of the lower extremity, the first compression zone extends from the first proximal end, distally away from a core of the user, posteriorly across a posterior portion of the one or more articles of clothing, and proximally toward the core of the user and anteriorly to the second proximal end such that a distal-most portion of the first compression zone is disposed at the posterior portion of the one or more articles of clothing.
