Level of Comfort: Artificial and Natural Shoe Materials.
This problem is especially acute in relation with the depletion and shortage of natural raw materials including natural and synthetic fibers and fibrous materials being traditional raw materials for light industry.
On the other hand, the advances in science and technology make contribution to the emergence of alternative materials: artificial and synthetic leathers and fibers being ready available and cheaper, as well as nanofibers and polymers further expanding the assortment of materials.
Hygienic properties of these materials were determined by standard methods of testing of shoe materials [8, 9].

Fig.1 Heat storage materials with expanded graphite Fig.2 Scanning electron microscope photograph of the expanded graphite After differential scanning calorimetry, the transition temperature of phase change materials with expanded graphite is 58.544 ℃, phase change enthalpy is 307.762 kJ/kg.
The transition temperature of phase change materials without expanded graphite is 63.71 ℃, and the phase change enthalpy is 311.997 kJ/kg.
The reason is that the expanded graphite has a high thermal conductivity and heat storage and release rate of the composite phase change materials is improved, in transfer process.
Phase change materials were made into a square plate, size 260 mm× 260 mm× 20 mm(Fig. 7).
