Sir Isaac
Sir Isaac Guidance Trainer
The Newton Isaac Guidance Trainer has been awarded 'Run Shoe of the Year' in the 220 Triathlon 2012 Awards for the second year running. The award-winning member of 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.
"I have been doing triathlon for some years and have always done OK but my running always let me down. Despite some coaching and reading countless articles it never really improved, until I donned some Newtons. I read the really useful tips on your web site and off I set… So far I've seen a 10 % improvement on my PB and they also got me to the Triathlon World Championships in Beijing representing GB which I would never have dreamed of doing before when I was a non Newton runner!"
Stephen, Sir Isaac wearer
