The GEL-KAYANO™ 29 shoe helps create a stable running experience and a more responsive feel underfoot.Featuring a low-profile external heel counter, this piece comfortably cradles your foot with advanced rearfoot support. We also updated the midsole with FF BLAST™ Plus cushioning. This helps keep the shoe lightweight while creating a more energized rebound in each step. A LITETRUSS™ stability feature is placed on the midsole’s inside angle. It’s designed to help keep your foot from rolling too far inward during your stride. Happy to answer any questions!
