When standing we should have a sensation of being more in our heels than the front of the foot. However, there should be no tendency to tighten the toes or lift them off the floor. Let the toes lie freely and allow the whole foot to 'soften'. Let the weight go down 'into' the floor so your feel grounded. This gives a firm base from which to think of lengthening upwards. Free your ankles so there is a little sway available to help discover upright balance. In order to enjoy standing without strain we should never get fixed in position.
