Think of the Nike Free RN Distance as a mash up of the Free 3.0 and the Lunar Tempo. The Free RN Distance borrows the 4mm heel-toe offset from the Free 3.0, but has more midsole under foot. In fact, the Free RN Distance is 2-3mm thicker in the forefoot than the Free 3.0 and Lunar Tempo. Like other Free shoes, the Free RN Distance has a heavily siped midsole/outsole (thinly cut grooves), which delivers tremendous flexibility. The pattern of siping is multi-directional and similar to the most recent Free shoes. While the center of the midfoot is not siped, and the resultant shapes are larger than other Free shoes, the sensation of flexibility and adaptability seems the same.From the Lunar Tempo, the Free RN Distance borrows a modified, accordion-like midsole structure, which delivers a soft, compliant feel. Furthermore, the Free RN Distance has a Lunar core foam midsole interior, which delivers a much softer feel than any previous Free model. Where some runners may have felt Free shoes lacked ample cushioning for longer runs, the Free RN Distance, with its thicker sole and Lunar cushioning, welcomes longer runs.Similar to other Free Shoes, the Free RN Distance has a close-to-the-foot fit. The midfoot and forefoot are shallow and provide a snug fit for medium to narrow feet. If you have a high instep, thick, full volume feet, or wider feet, this shoe is not going to be a good fit. While the toe-box is shallow, there is more room around the ends of the toes than other Free shoes and the pointy, super shallow Lunar Tempo. Your standard running shoe size should work well for this shoe.Immediately the shoes felt very soft underfoot. The upper felt quite snug in the midfoot and forefoot, but the heel felt loose and there was plenty of length for my toes. Walking around I could feel the arch structure of the shoe. It wasn’t uncomfortable, simply noticeable, which is something I like. The shoes still felt quite soft walking in them, the heel did not slip, and the upper moved well with the foot without having any pressure points or creasing issues.
