Sorry, you are right, there is no issue with the leg itself, the problem is with shoes, when wearing them does the texture stretching happen on lizard females. And it only happens when moving, or rather i cant zoom in enough to see it during the idle animation, but it is quite glaring when running. Also, the armor looks like a hoops on the lizard female's leg if it helps. Although i don't remember because it was a long time ago since i last played this game but it may also happen with other boots as well. The stretching itself happens near the knee area.
