SelectFlex develops adjustable orthotic insoles built around its patented PowerLift Arch technology, which dynamically changes arch support as the wearer moves. The company says its engineers and product designers developed the system through a collaborative partnership with a U.S. medical orthotics manufacturer, and a 2020 Quinnipiac University Motion Analysis Lab study measured increased arch support from the technology. Its arch-control insole received Industrial Safety & Hygiene News’ Best Foot Protection Product award for 2020.
