Nike Free 5.0+ Shield Running Shoes. The Nike Free 5.0+ Shield Running Shoes have good flexibility, a low profile (higher than 3.0 and 4.0), and great stability. This shoe offers a natural barefoot-like feel while still providing the same protection of a traditional shoe. Featuring less flexibility and a more supportive upper, the 5.0+ is one of the more durable shoes compared to the two previous Nike Frees. This version of the Free has been engineered with a three-layer mesh upper, repelling water without sacrificing weight or breathability. So buy this Nike Free 5.0+ Shield Running Shoes Now £89.99!
