The Xelero X-GPS XR415 provides unparalleled support and functionality. The enhanced Xelero technology incorporates a “Guidance Propulsion System”. The Propulsion element cradles the rear foot and extends forward to guide the foot into a neutral position thought the gait cycle. The carbon fiber “Slingshot” plate provides torsional stability, keeping the foot in alignment, and helps to reduce impact pressure. The dual layer “X-Lite” midsole provides cushioning, under the foot, and speeds up heel to toe transition when walking or running. The X-GPS is lighter weight than some of our other Xelero shoes and the only motion control/stability shoe in the market with rearfoot and forefoot stability. Ideally suited for running and walking.
