NEWTON SIR ISAAC S STABILITY SHOES

Offering intelligent control, the Sir Isaac stability guidance trainer is designed for runners of all levels, including beginners, who are committed to natural form running and need medial posting for mild pronation. It is ideal for beginning runners, people who run/walk or runners transitioning from a heavy heel strike to a comfortable midfoot landing position. Whether you follow Chi, Pose, Evolution, barefoot running or just want to run better, the Sir Isaac S allows you to run naturally, with greater efficiency and less overuse injuries (like Achilles tendonitis and plantar fasciitis). Recommended for any distance and general fitness, walking or working out in the gym.
