The draw: Encourages quick turnover

While it’s hard to believe Newton is already celebrating its 10-year anniversary, the latest version of the hallmark Gravity trainer reinvigorates the innovative vibe around which the brand was launched. Most prominently, a new layer of foam—aptly called Newtonium foam—adds to the already energetic and lively ride which comes from Newton’s five-lug propulsion system in the forefoot, designed to discourage heel striking. A new, flexible mesh tongue enhances comfort.
