This sandal with a custom insole insert was designed from the countless people over the years that have to wear shoes or insoles that aim to benefit the health of their feet. We designed a recycled cork/rubber sandal insole insert with a company that does medical inserts, trying to find the best most comfortable insole we could make. It is our comfort walking sandal, not to be confused with the original jc. also with super flex vibram sole. *Important note, this is a re-worked jc, it is nothing like the original jc, only in appearance, it is taller, heavier, and contains more rope. The sandal insert will not fit in our regular jc as we had to build a cup and adjust straps for the insole. black color, black sole, insert cork.
