Overview of this review
I bought this model last winter intrigued by its innovative design which looked like a super comfy and fast shoe to me. Wow, these shoes feel like wearing a sock. It gives you freedom of movement with still a little support on the ankle.
Regarding the design, I’d suggest to use them only with winter tights because they look quite goofy with shorts. Time to run!
As expected, the toe box is a little narrow, but it’s quite usual for Nike running shoes. I also felt the 10mm drop was a bit too much for this kind of "free running" shoe type.
The whole upper part is actually a single one. This is for sure the best part of the shoe.
There's a soft feeling embracing your feet up to the ankles. You could even run unlaced, but the lace actually helps you to find that perfect fit you are looking for.
Habitual testing route (flat+hilly - road+trail).
Since this was the shield version, I’ve been happy to make my first run in a rainy and cold day. Water resistance passed the test. It wasn’t raining heavily, but my feet were dry by the end of an 8-mile run in mud and jumping in some puddles.
I was a bit deceived by their design regarding the cushioning. They seemed much bumpier when I first saw them, but in the end, they were not even close to the feeling you can get from a Nike Free RN.
However, I was really surprised about their grip on the wet surface, and even on trails, the shoe does a great job considering it's not meant for road running. I’ve also noticed that foot stability isn’t perfect while making turns. You sometimes feel like your foot is going beyond the sole.
I wanted to test them on a long run before a race. After a couple of runs, I wasn’t so confident like I’ve been with other shoes, so I decided to go for a half marathon test at a tempo pace (4:10/km) before running a proper race.
Feelings were really good until halfway. On the second part, shoes started to feel heavier, and the thick sole wasn’t so bouncy as I wished. I was a bit annoyed by the high drop and the narrow toe box pushing on the little toe.
The outsole has a great grip on dry and wet roads. It also gives you decent confidence on simple trails.
I consider this a good running shoe which I personally use mostly for training during winter time and bad weather conditions. I wouldn’t use it for longer distances than 15k.
There is still room for improvement, especially on the toe box and sole but the "sock feeling" is great and makes it a special shoe.
Updates to Nike LunarEpic Flyknit Shield
- Nike almost always lives up to its reputation by continually looking for ways to improve their footwear, even their most popular and best-selling shoes. In the LunarEpic Flyknit it gets a modified upper that is now coated with TPU water-repellent material and a water-resistant cleatie for the inclement weather. Not only will the update protect the foot against the elements, it also gives a bit of warmth when the need calls for it.
- Without question, the mid-rise Flyknit upper is the most glaring feature of the shoe. It takes Nike’s concept of a sock-like fit to a whole new level. The runner gets a wraparound feel all the way from the forefoot to just above the ankle. It also enhances support and stability, especially from a very light shoe.
- The Flyknit is designed to give support and flexibility in the right areas. Without the use of overlays, the support is still there while giving the runner the freedom to have a natural ride.
Size and fit
The snug, and racing shoe kind of feel is very evident in the Shield version of the Nike LunarEpic Flyknit. It naturally becomes a favorite for those with medium to slightly narrower feet because of how it hugs the foot. There is decent room in the forefoot for the toes to splay. The heel and the midfoot are comfortably locked down. It runs true to size.
The innovation of the Swoosh in the LunarEpic Flyknit Shield continues in the underfoot. With a siped outsole that is laser-cut, the shoe gets excellent flexibility. A very sticky rubber is used in the outsole for superior traction, even on wet surfaces. The outsole layout also gives a boost in the cushioning due to the design and location of the well-articulated pods.
The same laser-cut design on the outsole is also utilized in the fused Lunarlon foam that covers the length of the midsole. It gives the shoe another element of flexibility and boosts the smoothness of the gait cycle.
The Flyknit offers good breathability and covers the foot from the forefoot to the lower leg in a one-piece structure. Nike uses this design to increase the support and stability of the shoe. In this version of the LunarEpic Flynit, the Shield technology gives water resistance to make it almost an all-weather runner. The Flywire cables provide optimal midfoot security and support.
