Nike Free Run+2 Review

As minimalist running has become more popular, a category of running shoes that straddle the line between traditional and barefoot-style shoes (like the Vibram FiveFingers Bikila) has emerged. These shoes are lightweight, have minimal support features and maximum flexibility, but provide more protection than a true barefoot-type shoe. Shoes in the Nike Free series are sometimes referred to as "reduced running shoes" or "transitional minimalist running shoes," and the Free Run+ 2 falls into this category. Since its original incarnation, the model has earned a loyal following. In fact, Nike boasts of two clinical studies that say the shoe helps increase the activity of smaller muscle groups, which may help boost running efficiency and decrease pain and injury. The Free Run+ 2 was introduced in April 2011, and reviewers say the shoe is equal to if not better than the previous incarnation.

At about 9 ounces (for the men's version), the Nike Free Run+ 2 isn't the lightest minimalist-style running shoe available. Plus, it sits 25 mm off the ground -- 10 mm lower than traditional running shoes but substantially higher than other minimalist shoes. The Vibram FiveFingers Bikila, by comparison, sits just 7.2 mm off the ground. Despite these issues, reviewers say the shoe's comfort and flexibility make the Free Run+ 2 an ideal pick for those interested in more minimalist running. The shoe is often praised for its roomy toebox, minimal seams and no-socks-needed interior. Some users say that runners who like more stability features should consider a more traditional running shoe. Plus, while the Free Run+ 2 is ideal for shorter mileage or as a race-day shoe, it should be alternated with other styles or models long term.
