Rachel Ferguson established Synxsole in 2011 alongside fellow podiatrist Marie Ann Lewis, with the business initially selling insoles products to practitioners. In 2015, Ms Ferguson made a deal on TV show Shark Tank with Sydney-based businessman Andrew Banks, who invested $100,000 in Synxsole in exchange for 45 per cent ownership. He remains an investor in the company. The business has since developed four ranges – Synxsole, Syngeli, Synxlace and Synxplus – with 19 products that target a number of foot and body-related concerns. The company rebranded as Synxbody in 2020.
