Benefits Lunarlon cushioning for an incredibly soft and springy ride Ultra-light Flywire threads cradle the foot for an adaptive, glove-like fit Dynamic Support provides just the stability you need Nike+ makes it easy to track, share and compare your runs Weight: 10 ounces (men's size 10) Fit Strong, ultra-lightweight dynamic Flywire on the shoe's upper is adjustable through the laces and wraps the midfoot and arch for a personalized, glove-like fit. An inner sleeve wraps around the entire foot for a plush, comfortable fit and easy on and off. Stability The latest LunarGlide features Dynamic Support in the midsole for stability without the added weight or stiffness of a traditional medial post. It also has a floating heel-support clip that moves with you and helps keep the back of the foot from rolling inward or outward upon landing to moderate excessive pronation. The clip wraps underfoot and tenses up as weight is applied to lock down the heel. Nike+ The LIVESTRONG LunarGlide+ 4 is Nike+ ready, so you can easily track, share and compare your runs.
