One of the Jumpman's five upcoming React-cushioned silhouettes, the Proto-React is eerily similar to the Apex-Utility and even employs the exact same sole unit and upper shroud. The key difference here is the lack of the Apex-Utility's Flyknit AJ1 beneath the shroud. Instead, these appear to employ a different inner bootie that streamlines things a bit. It'll be interesting to see which silhouette consumers gravitate to more toward considering just how similar they are.
The Proto-React is currently slated to launch in 2019.
