    Performance, comfort and support with foot cooling technologies
    SpenCool™ Top Cloth contains a special low-temperature jade obtained from natural resources that allows the fiber to effectively slow down temperature rise when the cloth is exposed to heat (strenuous activity such as running, athletics etc.) and then quickly radiate the heat to cool down after the heat source is removed (cessation of strenuous activities)
  • When exposed to heat over a period of time can effectively drop the temperature 2-3°C (1.8° - 3.6° F)
  • The concave heel pad allows for compression and thus displacement of air from the concave area during heel strike while running
  • As the foot progresses from heel strike to toe off, the air channels collapse under the weight of the runner and air is moved towards the forefoot 
  • Air vent holes provide passage for air transfer between the top and bottom of the insole
  • Magnesium Oxide (MgO) added as a filler for EVA material to improve the thermal conductivity of the EVA
  • This interface is where the heat is dissipated by convection, conduction and radiation
