While the upper has some similarities to the Chris Paul Basketball shoes, it also features some of the biggest differences – and in my opinion, improvements. The Chris Paul Basketball shoes strap offered some midfoot security, but wasn’t entirely necessary. I lace my shoes tightly enough that I wasn’t really getting much support from the strap.The other big difference from the Nike Zoom KD II, in terms of the upper, is the addition of Flywire. Like pretty much every aspect of the KD III, the use of Flywire has been highly targeted. From a cushioning standpoint, the Chris Paul Basketball shoes and III are very similar. A full-width 6mm Zoom bag offers as-good-as-it-gets responsiveness in the forefoot, while Phylon is responsible for the impact protection in the rest of the tooling.
