Now as a huge fan of the foampostie shoe & brand I think I can say they are doing too much. Though at this point the “Glowposite” is just a concept, I do see Nike eventually trying to bring this out in stores. The upper is a 3M synthetic foamposite material to give it a graphite look for the day look & bright white/silver look for the night look. The sole is a glow in the dark material that charges it’s self when exposed to light, and will put & bright yellow light when exposed to darkness. I may have to see a finished product before I pass the final judgment on these but for now I’m cool.
