We've reimagined this workhorse running style with less weight and a smoother heel-to-toe transition. ​ The midsole is updated with a full-length FF BLAST™ PLUS cushioning unit and PureGEL® technology. These features help provide a more energized toe-off with cloud-like softness underfoot. ​ Meanwhile, the 3D GUIDANCE SYSTEM™ consists of wider basenets and an increased heel bevel and forefoot flare. As a result, you'll experience a silky-smooth transition from footstrike to toe-off.
