Free 5.0 Sole
A Nike Free 5.0 plays to the masses, offering midrange cushioning that lands right in the middle of running barefoot and running in a traditional running shoe. The Free 5.0 sole features the slits and flexibility that the franchise is known for, offering a mid-level approach to barefoot running. This same sole style is also used on the Nike Free Inneva Woven for reference.
Nike+ Compatibility
Like many other Swoosh-stamped products on the market, the Nike Free Flyknit is Nike+ compatible. This allows wearers to track performance metrics, compete with friends and set goals, while syncing with mobile devices, Nike+ accessories and social media platforms.
