Socks with lateral plantar arches

Abstract

The present invention relates to a sock having a lateral plantar arch recess, to a sock having the lateral plantar arch recess in which a certain region of a lateral plantar arch support configured to support a lateral plantar arch is formed at a bottom surface of the sock with the lateral plantar arch recess which is recessed upwardly from a lower surface by a certain thickness, so that the center of gravity of a wearer of the sock is moved rearward and outward while the wearer is standing, thereby reducing the load applied to the hallux, and the center of gravity of the wearer of the sock is moved to between first and second metatarsal bones sequentially through calcaneus, a cuboid bone, and a fifth metatarsal bone while the wearer is walking, thereby delaying pronation as much as possible and causing supination to occur more easily after pronation.

AI Technical Summary

Benefits of technology

The present invention is a sock with a recess on the arch of the foot. This recess increases the space available for the arch and reduces the pressure on the toe. This makes it easier for the foot to relax and bend naturally while walking or running. This design helps to prevent pain and fatigue while promoting better performance.

Problems solved by technology

However, when a medial plantar arch is unnecessarily over-collapsed (hyper-pronation), various orthopedic disorders occur in the lower extremities.

Such an excessive distortion pattern causes muscle imbalances that lead to foot, ankle, knee, hip, and back pain, and leads to a change in an alignment of the tibia, femur, and pelvis, thereby increasing the risk of injury to soft tissues (Achilles tendon, pedal arches, patellar-tendon, and iliotibial band) due to the accumulation of internal rotation stress in the pelvis and lower back.

The excessive distortion pattern also compresses the subtalar joint, the patellar joint, the tibiofemoral joint, the iliofemoral joint, and the sacroiliac joint, thereby causing an anterior pelvic tilt of the pelvis.

Pronation of 2° to 3° of a foot causes 20% to 30% of pelvic inclination when standing and 50% to 70% of anterior pelvic tilt when walking, thereby resulting in an imbalanced back and spine.
