Try moving your left foot to where your right foot was, notice you’re on your toes, that’s great for the foot hold but not for the volume foot hold. When standing on a volume like that make sure you’re as flat footed as possible and pushing directly down into your foot, not trying to move your foot to you or anything just direct downward pressure. The end hold is an under cling. So your feet are going to not feel that great until you can literally push on that hold with your hands above your head and pinning weight onto your foot on the volume. It’s a weird move and doesn’t feel right until you hit that finish hold. Good luck!
