AI Technical Summary
Technical Problem
Existing garments fail to effectively prevent external rotation of the lower leg, leading to outward pointing toes and increased knee strain, especially during activities like walking and squatting.
Method used
A garment design featuring two band-shaped tightening fabrics with strong tightening forces, extending from the inner side of the lower leg to the thigh, intersecting at the lateral epicondyle of the femur, and incorporating elastic base fabrics to maintain close contact, with the second tightening portion angled to pull the fibula forward relative to the femur, guiding internal rotation.
Benefits of technology
Prevents external rotation of the lower leg, aligns the direction of the knee and toes, reducing knee strain and maintaining proper posture during movement.

Abstract
To provide a garment which prevents external rotation of a lower thigh, which tends to occur when walking, and makes toes straight.SOLUTION: A garment is formed of at least two belt-like strong tightening fabrics having strong tightening force and is worn in almost close contact with a wearer's surface. The strong tightening fabric has: a belt-like first strong tightening part which passes through the vicinity of the tibial tuberosity from a height slightly below the tibial tuberosity on the inside of the lower thigh, passes through the outer epicondyle of a thighbone, and extends from the back of the knee joint to the inner thigh portion above a knee joint space; and a belt-like second strong tightening part which is formed of a straight first portion which covers the fibula starting from a lower part in a longitudinal direction of the fibula up to the fibula head and extends to the outer epicondyle of the thighbone and a straight second portion which is changed into a prescribed angle at the outer epicondyle of the thighbone and extends from the outer epicondyle of the thighbone to the inner thigh portion above the knee joint space. The first strong tightening part and the second strong tightening part are intersected at the outer epicondyle of the thighbone.SELECTED DRAWING: Figure 1
