left without a doubt but right ok,left just better, they look more slender and slim, the nail polish is good, and a indication that she takes care of her feet, so they are tickle worthy, the right on the other hand look a bit clumsy by comparison,thicker and may be not looked after quite so well,both are better than mine,
that is my take on it, more pics from many angles for both sets of feet would be a better situation.Thus giving a better opinion, but both are ok.
Maybe the right feet are a guys and the left a girls, no offence if i'am wrong just a idea.
