A heat-insulation multilayer material is made up of three layers: an inner layer (1), in contact with the foot when in use, made of fabric and/or leather and/or imitation leather; an intermediate layer (2) made of needle-punched staple synthetic microfibres and containing expanded microspheres (21); an outer layer (3) which is made of fibres having high moisture absorption power and which, in use, is the furthest from the foot, Some of the fibres of the outer layer extend through the intermediate layer substantially up to the interface with the inner layer to form micro-channels (31) for displacing the moisture from the layer which is in contact with the foot to the outermost layer. The material has a high capacity of transporting moisture outwards, is light in weight and relatively reduced in thickness compared to prior art heat insulation materials. It is not easily compressible, nevertheless having satisfactory breathability, but has an elastic effect which allows it to recover at least 80-90% of its initial thickness. |
