X-leg is just an expression for many reasons. Such as varus, knee joint inflammation and so on. Do you mean children or adults? It can be corrected if the child's developmental period is not over. According to different types of reasons, the appropriate corrective method is to use orthopedic shoes or knee brace. Adult's words can't be corrected, the bone development has been finalized, and only surgery can be performed. Need to go to an orthopedic surgeon for detailed consultation, not a certain kind of shoes or insoles can be corrected.

I hope my answer is helpful to you.
