I have moderate X-legs, and I sleep with my legs tied every day. I use that thick hair band, with one leg tied to my ankle and one leg tied to the other. At first, it was extremely painful and I couldn't sleep well. It turned out that it did have some effect. If you take a splint to the orthopedic department of the hospital, there will be plastic instruments.

The most important thing is to walk correctly, focus on the center of the foot, and don't be outside eight or inside eight. Or you can bend it back when you get it back.

This should be a healthier way, but the change is really slow, so be patient.

I've heard of osteopathy upstairs. Some people said it was useful, others said it was useless, so I didn't try.
