  • The 6th edition of one of Nike’s most popular middle-distance shoes in the LunarSpider R presents a couple of changes that should take its performance to another level. Most prominent of the change is the presence of bigger holes in the mesh. Runners are assured of a more breathable shoe with this update.
  • Nike also uses several bands to group the Flywire cables together. Experts say that this gives the latest LunarSpider R model better hold and influence in getting a more personalized and comfortable fit.
  • An almost insignificant overlay extends from the midfoot to the heel for added heel support. This is still quite flexible, which should not compromise the upper area’s ability to adapt to the foot.
  • For aesthetic value, Nike transferred the oversized Swoosh logo smack in the midfoot as opposed to the previous version where the logo sits near the ankle collar.

The fit and sizing are reminiscent of the previous version, which is average in the heel and a little narrow in the forefoot. Many of Nike’s performance shoes are a tad narrow in this area and the LunarSpider R 6 fits that mold. Runners who love more toe room may have to go half a size up. This is a unisex shoe in men’s sizes. The available sizes are from 5 to 15.

The main element in the outsole that offers durability is Nike’s own BRS 1000 carbon rubber. Nike has incorporated a TPU Pebax Shank in the forefoot for added protection, better toe-offs, and to add to the outsoles grip on the road. There are also forefoot nodes that add a responsive feel to the shoe.

A co-molded Lunarlon occupies the midsole for resilient and responsive cushioning. This midsole material is also used in some best-selling Nike running shoes.

An upper with slightly larger holes and synthetic overlays deliver the right blend of superior breathability and lightweight support. The Flywire cables that are both connected to the laces and the sole provide different levels of comfort and support for the runner.
