Since I was recently trying to figure out how to correctly depict a knight on horseback, I had a look at some illustrations of medieval riders. They often seem to hold their legs almost straight and kind of point them forward. Here is a paper which depicts the evolution of the position on horsbeack over the centuries (p. 4):
Also this site refers to a book which states that at least warhorses were ridden in a special fashion.

Actually I donāt think this is a problem even if it is not 100% correct. I guess it wonāt break immersion and the quality of the animations is more imporant. Nevertheless I think it is an interesting topic. Maybe someone with a more solid knowledge of the topic (I canāt even ride a horse) can provide some explanations. Was this style of riding only for warhorses during battles or was this also used when travelling?
