Pokemon: XY Foot Festival

Welcome back to the Foot Festival series. After my little rant on Iris from the BW Foot Festival, let's head to Kalos in XY based on the games of the same name from the Nintendo 3DS. This is only from Seasons 17 to 19 (XY to XYZ). Again, I don't know much on the characters and Pokemon here with Serena the one I know the most and I prefer her long hair due to my love for long haired girls. Whose female trainers' do you want to play with in terms of their feet?
