If you exercise to correct O-legs and chicken breasts,

Excuse me, is your O-leg serious? Whether it's the inner figure of eight, the X-leg or the heel valgus, it's all because of the incorrect stress on the foot, which leads to the negative force line of the body and the incorrect stress point when walking. If you insist on correction, it is ok. It is best to use it with correction tape or correction tape, and the effect will be better.
