The invention concerns a preform and a device for cooperating with a lower limb member so as to provide a correction to the limb member. The invention also concerns a method and an apparatus for manufacturing the device. The preform comprises a base, a surface linked to the top face of the base, for cooperation with the lower limb; and at least one inflatable chamber formed by a flexible and liquid-impervious membrane sealed to the concave top face of the base. Injection of a fluid composition of curable material, while the lower limb member is in contact with the surface so as to inflate the at least one inflatable chamber is performed until the correction is obtained, the composition being then cured in-situ into a cured material.
