Abstract
A custom moldable insole comprising a first chamber containing a silicone base and a second chamber containing a catalyst. Both fluids are forced to pass though a shared static mixing channel where they will thoroughly mix and flow into a third chamber. The third chamber is a continuation of the mixer that opens up into a bag to hold the silicone as it flows to the arch and metatarsal areas of the foot in the upper layer of the insole. Within a few minutes as the user stands wearing the shoe the silicone cures to the shape of the bottom of the wearers foot providing increase support and comfort.
