The newest addition to the Newton family offers intelligent control for all foot types. The Sir & Lady Isaac is a neutral guidance trainer designed for runners committed to improving their running form to the more efficient midfoot/forefoot running style. I managed to get a sneak preview of “The Isaac” at the Newton Running booth at the recent Rock ‘n’ Roll 1/2 Marathon expo, and was impressed by the thinking behind the shoe.
The main difference is the beveled lugs in the forefoot area of the shoe, which *should* help runners make the transition to a more efficient midfoot/forefoot technique.
From the Newton web site:
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 Rubber Outersole: increases durability
Closed Mesh on Upper: keeps small debris out

At $149.00, the Isaac is also a little cheaper than their two performance trainers — the Gravitas and Motus are both priced at $175.00 — which will probably entice quite a few more people to jump on the Newton bandwagon so-to-speak. Newton Running are currently offering a FREE shipping promotion on the Isaac too – click on the image above to take advantage of the offer.
Don’t forget, you can always take advantage of their 30 Day Return Policy and Guarantee.
