Since the day Dongguan S-King Insoles Limited began our export business, we have realized the importance of gaining a CO which is usually issued for goods that are being sold abroad as a permanent export. Our CO is granted by national Chambers of Commerce with legal sign and stamp on. This document is an important document used in global trade to confirm the country of origin where our goods have actually been manufactured or processed. With it, the import duties and tariffs can be reduced or eliminated in the country of import.

After the successful introduction of high technology, S-King is more confident to produce high quality heel cushion. S-King Insoles's plantar fasciitis socks series are created based on unremitting efforts. Its structure is designed for maximum efficiency and easiest ongoing maintenance for the lowest total cost in both installation and everyday use. The S-King heated insoles keep your feet warm for 4-8 hours per charge. As long as there is need, S-King Insoles will be ready to help our customers to solve any problems happened to best shoe insoles. S-King insoles have to go through more than 1,000,000 times of anti-bending tests.
