Toes do not bend when they are being pulled tight. This happens when the bedroom is too cold, and feet are exposed to cold night air and one has severely painful foot and toe cramps in the early morning.
It may be difficult to bend the toes when they remain motionless and stiff after driving very long distances in an automatic transmission vehicle, especially if the shoes are too stiff.
Soak the toes in hot water in the bathtub at the motel. Then bend the toes.
