We conducted human subjects testing to gather feedback on the comfort and stability of potential midsole materials and structures. We also rigorously tested their physical properties to make sure they would be able to withstand the forces of daily use. We settled on FilaFlex Foamy, a filament which expands as it’s extruded, reducing the mass of the midsole, infused with silicone gel for extra support.
