A below-knee orthosis with fastening devices for fastening the orthosis to the foot and to the lower leg includes an L-shaped support spring made of a resilient material. The L-shaped support spring has an upright branch that defines a contact plane, and is intended to bear on the dorsal aspect of the lower leg. The lower end of the upright branch is adjoined by a horizontal branch designed to engage under the foot. The below-knee orthosis allows for an improved heel-to-toe behavior in the material of the support spring which takes into account the natural outward position of the foot by the upright branch being twisted in the lower area in such a way that the horizontal branch continuing the lower end is turned outward by an angle α from the plane lying perpendicular to the contact plane of the upright branch above the twisted lower area.
