Our company developed an unique rubber for dry and wet ice surface. The rubber itself has great grip without traditional metal studs. You can find the video above our website shows the tester walks on the ice with and without our special rubber. The tester wears with regular shoes can't even walk on the steep ice surface. After changing with our special rubber shoes, the tester can walk and jog on the wet ice surface without falling.

     Slip resistance is one of the most important functions for the sole and its performance directly affects the safety. Yi Chang designs the unique rubber compound to increase the slip resistance; especially on the wet floor. For more information about the test on anti-slip shoes, please visit our video section.

      Yi Chang manufactures special spiked sole which is designed by Han-Jing Wu. Compare to the traditional spikes, the new spikes are fully integrated with outsole. The sole not only can reach both comfort and flexibility, but also do perform high shedding resistance and anti-slip functions.

      Ever since the rise of eco-conscious, people are more aware of production produced from recycle materials . Materials from recycle not only reduce environmental pollution, but also lower the costs of production process. The process of producing the recycle outsoles (insoles) is to grind the entire shoes and mix it with rubber. For more information about the production process, please visit our video section.

     Midsole made of EVA provides a lightweight sole with more cushioning. Also, rubber pieces attached on EVA can enhance abrasion.
