Therapeutic dynamic retention/compression sock for use during practicing sports, has rigid zones enclosing elastic zone to create gusset zone to propel blood towards top, and envelope extended from foot till top of calf or till top of thigh

摘要

The sock has a knitted or woven envelope extended from a foot till the top of the calf or till the top of the thigh. The envelope contains elastic threads having different elasticity properties for tensioning knitting. Two rigid zones (1, 3) enclose an elastic zone to create a gusset zone to propel blood towards the top. One of the rigid zones is supported on a tibial edge and is extended from a patella tip till the base of the tibia. The other rigid zone surrounds a calf pump from the top towards the bottom. The elastic zone is extended between the rigid zones.
