It gets the job done and blends into the heel with a small dab of reflective material just at the bottom for added safety.
It’s a step down in intensity from the Lunarglide 7s which had a pretty big plastic loop running around the heel. The LunarGlide 8’s smooth external heel counter combined with the springy and plush foam in the heel gives the shoe a nice look and a nice fit.
The last notable feature on the upper is the use of Flywire. Each shoelace loops through a thick string that attaches to the sole of the shoe to give your feet a snug fit.
I’ve had some gripes with Flyknit in the past deteriorating on me, but I think the newest version is fairly robust and will hold up to several hundred miles of running.
