Nike Air Max 90 Current Flywire TZHere is another updated version of the classic Air Max 90. The Nike Air Max 90 Current Flywire sports innovative technology making it the lightest running model in the Air Max line. Flywire technology uses thin interwoven filaments to provide lightweight durability and support. When you combine that with an all over breathable mesh upper and a Nike Free-inspired outsole, it makes for a remarkable sneaker. Plus, they look great because Nike remained true to the original Air Max 90 design.
