The newest addition to the Newton family offers intelligent control for all foot types. The Isaac is a neutral guidance trainer designed for runners committed to improving their running form to the more efficient midfoot/forefoot running style.

How does the Guidance Trainer differ from the Performance Trainer?

• Beveled Heel and Toe: helps guide runner easily into the midfoot/forefoot
• Beveled Lugs: smoother, stable feel that is more gradual in the forefoot
• Wider midfoot/forefoot and lugs: adds stability and creates a softer feel
• Midfoot Chassis/Shank: adds support and stability
• Carbon Runner Outersole: increases durability
• Closed Mesh on Upper: keeps small debris out
