The Nike Air Tech Challenge 4 is finally back. But don’t get too excited, Tech Challenge fans, because it’s probably not in the form you’ve long been waiting for. With an interesting move, not only is the first return of Andre Agassi’s Tech Challenge 4 the low-top instead of the more popular mid-top version, they don’t even go with one of the original vibrant multi-colored versions that made the shoe what it was. Instead, it’s a muted tonal Anthracite colorway on an all-white sole. They did get just a little pizzazz, however, with speckling on the midsole. So, what’s your take on the first return of the Tech Challenge 4? Let us know in the comments below.
