It's just a palliative, not a permanent cure. Thumb valgus is largely caused by acquired bad habits. Practice walking posture more.

Hallux valgus is a deformity of skeletal structure. The foot is a stable and elastic structure composed of a bunch of small bones, just like a forked branch. When you hold it in your hand, it looks effective on the surface, but once you let it go, it will return to its original state. Our wishes are good, but the reality is invalid, don't you believe it? Go and pinch the forked branches back first. The tree grows crooked, and sometimes it can support itself, because it keeps growing. Therefore, an Australian doctor is studying the effect of orthosis on hallux valgus in children. But the feet of adults are no longer growing, so orthoses are useless and theoretically unreasonable. Ligaments and bones will not change because of your bondage.
