The latest multi-colored rendition of the Nike Flyknit Trainer is finally reaching retailers after months of teasers online.. Featuring a bright, multi-colored upper, it's the blue glow stripe running the length of the midsole that adds some extra visual oomph to the design. The knit upper is complimented by black Dynamic Flywire across the sides, a black tongue and a white Swoosh. Look for these at select retailers including Overkill.
