The Xelero X-GPS WR provides unparalleled support and functionality. The enhanced Xelero technology incorporates a “Guidance Propulsion System” with Aqua Max water resistant membrane lining that keeps the foot dry inclement conditions. The knit upper with molded overlay adds support and durability to tackle the most challenging environments. 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. X-GPS WR 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.
