Released May 2019, the Free RN 5.0 'Deep Royal Blue' supplemented Nike's running line with an ocean-inspired colorway ideal for summer. This low-profile sneaker is focused on flexibility, with a stretch-mesh upper and barefoot-like construction inspired by Stanford athletes who train shoeless on the campus golf course. Contributing to the anatomical feel is an out-turned back collar to protect the Achilles from irritation, and deep midsole/outsole sipes for full range of motion.
