The reasons why one leg feels long and the other leg feels short in practice are mostly due to incorrect standing posture, insufficient leg relaxation or insufficient leg strength. One suggestion, one test. If this happens, please adjust your posture slowly and try to relax your muscles and joints. Breathe naturally. Imagine that your feet take root like the ground and your body is as tall and straight as a pine tree. Wish you success!
