Evaluating how legs align when standing upright with feet together highlights distinct physical structural categories.
- Type A (Straight and Parallel): The thighs, knees, calves, and ankles touch gently with minimal gaps, reflecting classic symmetry, physical balance, and a grounded posture.
- Type B (Bow-Legged Alignment): The knees curve slightly outward while the ankles remain together, creating an open central space that indicates dynamic movement patterns.
- Type C (Knock-Knee Alignment): The knees touch comfortably while the lower legs and ankles separate slightly, forming a triangular lower gap.
- Type D (Overlap and Narrow Gap): The upper thighs and ankles touch while a subtle gap exists between the knees and lower calves.
