Foot Stretch

Sit where you can comfortably stretch your leg out. The knee does not need to be straight.
Start with the ankle fully flexed (dorsiflexion). Slowly articulate smoothly through all the segments of the foot and then toes until fully pointed (plantarflexion).
Lift and spread your toes back up and then slowly reverse the articulation back to your maximum dorsiflexion.
Do it at least 10 times, encouraging your foot to lengthen and free up through all the small joints.
Do the same on the other leg.
