This has been my experience with Nike ID shoes. I'm currently running in the Nike React Infinity Run Flyknit 2 which I custom designed and about 150 mile the shoe is really feeling heavy, clunky, with very little cushioning. Has this anyone else experienced this? I went to a running store and felt the soles of the same exact shoe and it felt much softer.
Is Nike using different foam, etc for the custom shoes.
I also want to add that I had the Nike LunarTempo's a few years back in an ID design they also felt "harder" than the standard/factory designs.
