This invention describes a shoe where both the upper and the outer sole are made from knitted materials. The outer sole is specifically knitted, and an insert with small bumps (knobs) on its bottom surface is placed next to this knitted outer sole to help with traction. The knitted outer sole can also include stability features created by precisely manipulating the yarns during the knitting process, potentially using rubberized yarns.
Why it matters: Since 2019, significant advancements in robotic 3D knitting machines and multi-material yarn integration have likely improved the precision and durability needed to produce complex knitted soles with integrated stability elements and rubberized yarns.
