Simply put, if you walk for a long time (the difference between the toes is more than 30 degrees), you will become an O-shaped leg with developed muscles on the outside of the leg, relaxed muscles on the inside and uncoordinated ligaments on the inside and outside of the knee.
In the same way, in the long run, the figure of eight will become an X-shaped leg. You have to figure out which leg looks good, and then go in that direction. . . .
