Abstract: There is provided a snow board shoe having a non- rigid structure so that bending and rotation are permitted in the area of the ankle but resistance to release loads, without substantial deformation of the sole, and the transmission of the forces applied by the athlete to the board, both transversely and longitudinally, are ensured by means of the insertion of a preshaped reinforcing element of semi-rigid plastics material which encloses the lower sheet of the upper and an edge portion of the associated arch support, wherein a reinforcing metal sheet or plate is inserted in the reinforcing element and the shoe is completed by a mid-sole of expanded plastics material interposed between the reinforcing element and the sole, the mid-sole being injected directly onto the mounted reinforcing element in such a manner as to surround it externally and partially internally.
