Released in May 2019, the Free RN 5.0 'Deep Royal Blue' is a new addition to Nike's running collection, providing a colorway that draws inspiration from the ocean - making it perfect for the summer season. This particular sneaker stands out due to its emphasis on flexibility, achieved through a stretch-mesh upper and a construction that closely mimics the feeling of being barefoot, which was influenced by the shoeless training practices of Stanford athletes on the campus golf course. For added comfort, the shoe features an out-turned back collar that provides protection for the Achilles and reduces irritation. Furthermore, the deep midsole and outsole sipes enable a full range of motion, enhancing the overall anatomical feel of the shoe.
