I have been running in Newton Gravity’s for about 6 weeks now. I have had some knee pain (old meniscus tear I never had repaired) flare up, but besides that, I have loved them. I wasn’t ready to race with them at Muskoka 70.3 and wore my Nike Vomero’s and actually had more pain, so I am sold on the Newtons. My question is, would the new Sir Isaac’s be a good choice to rotate with the Gravity and use the Sir Isaac for longer runs? I was rotating with my Vomero’s, but just like the Newton’s so much, I can’t run without them now. It has made running more enjoyable. Any help would be appreciated.
