Best Answer

Plantarflexion is a movement of the foot at the ankle joint downwards - ie. the whole foot is pointed downwards. Imagine standing up then raising yourself onto tip-toes and flexing the foot as far as it will go to stand as tall as you can. In this position your foot is plantarflexed.

This is the opposite of dorsiflexion where the foot is pulled 'upwards'.
