On the other end, I have the ability to voluntarily move my big toe away from the other toes in the horizontal plane of the foot. Like splaying toes, but just swinging the big toe sideways while the others are at rest. But, I can only do this on my right foot. It's like I have awareness of a muscle and tendon there that is just absent on the other foot. It was weird to realize this asymmetry at first when I was young.
