If the smart insoles were created using a traditional manufacturing process, the complete smart insoles with pressure sensors would have cost upwards of 100 thousand HK dollars and would only be durable for one year.

Both traditional insole customization and smart insole creation are a complicated process. Generally, insole customization manufacturing requires:

-impression molding from foam, silicon or plaster,
-thermoforming insole material in foot impression,
-correcting the insole and finishing.

The smart insole production additionally requires insole manufacturing and circuit integration setup. The challenge is, without moulding for a large batch order, the small batch producing or prototyping can only rely on hand making which will result in a very inaccurate layout.
