Suggest Remedy For Weak Ankles And Knees
Physical therapy.
Detailed Answer:
Hello and welcome,
The purpose of bracing parts of the body is usually just to decrease the stress on the area after an injury, until that injury heals. But the down side of braces is that if worn for a long duration, the associated muscles can get weaker - not stronger. So once the inflammation from an injury is down, exercises to make the area stronger are in order.
I would highly advise seeing a physical therapist for evaluation of your leg-foot alignment and also for ankle strengthening exercises. These usually include proprioception (position sense) training that can help for preventing further ankle injuries.
If your possible pigeon-toe is significant, the physical therapist may recommend you consult an orthopedic surgeon for evaluation. I doubt that your feet are significantly turned in or you would likely have noticed it by your age.
But I would first start with physical therapy.
I hope this information helps.
