There's been some posts/rumors lately about the 5%s or whatever they'll be called. Any word on what the actual differences are? Anything major? I've got a pair of the original (not-flyknit) 4%s and have used them for 2 marathons and was planning on using them for one more this fall.
Should I just pick up a pair of the flyknits now since they're available and use the my OG 4%s for some shorter races this summer for fun? Or is it worth holding out hope that the next-gen ones actually get released and are somewhat easy to get in time for a fall race?
