Overpronators will appreciate the solid stability and ample cushioning in the sleek Triax+ 12 road-running shoes with optional Nike+ data tracking capabilities. A Nike+ sensor speaks to your Apple iPod nano to track distance, time, pace and calories burned, then relays the info to you via the headphones. Waterproof and virtually unbreakable, the Nike+ sensor fits perfectly into the pocket under the left insole (sensor and iPod nano sold separately). Nylon mesh uppers with thermoplastic urethane overlays provide lightweight flexibility and breathability while firmly wrapping feet for a comfortable fit. Long-lasting polyurethane footbeds provide arch support, good fit and overall comfort. Midfoot support saddles enhance fit and stability; wicking nylon linings absorb excess moisture and dry fast. EVA midsoles and Zoom Air units in heels and forefeet soak up shock and provide a smooth transition to a responsive toe-off. Torsional rigidity and stability are provided by external thermoplastic urethane arch shanks to help control pronation. Multizone outsoles feature varying rubber durometers and flex grooves to improve traction, gait transition and overall comfort. BRS 1000 rubber in heels and Duralon rubber in forefeet supply solid traction, improved feel and durability on all types of surfaces. Reflective accents at toe and heel improve visibility in low light. . | 343983-061 | Footwear > Multi-Sport Footwear -- Women's > Road-Running Footwear
