I was watching one of Nightwing2303's recent videos, and he mentioned that the fuse layer everyone keeps talking about under the FK is actually additional glue that Nike uses to hold the flyknit together and stabilize the upper for more structure. Apparently that's why it feels stiff but becomes more flexible over time. A designer was telling him that with woven/synthetic uppers they just use varying amounts of glue on different areas of the shoe to provide structure where it's needed. If all of that's true, I guess it's still "real" flyknit, just stiffened up with glue to provide more structure for basketball/performance purposes. Definitely agree with you that ventilation is an issue though, but I also love the traction.
