How to judge Zhihu of leg type?

(1) If the ankles and knees can be close together and the legs are straight, they can be close to each other and the leg shape is normal;

2 if the knees can be close together, but the feet can't be close together, it is likely to be an X-shaped leg;

3 if the feet can be close together, but the knees can't be close together and the knees are straight, it is likely to be an O-shaped leg;

If your knees and feet are fine, but your calves (shins) are very apart, then you may have an X-O leg.
