Do you remember the Nike LeBron 20-5-5? That seems to be the sneaker from the Nike LeBron series that most closely lines up with this strange sample pair from at least a few years back. The shoe looks to be from the Cavs era (Note that the L23 logo shows up around the mid foot area) and utilizes a combination of mini straps and a backwards Swoosh that was still pretty foreign to LeBron shoes at that point. See the full wear-test sample after the break and tell us if you think these should have made their way to retail.
That looks like what would happen if the Shaqnosis & Kamikaze had a kid. Then the Trainer Max 2 & Huarache Trainer 94 had a kid. And then those kids met and had a kid. That design is all over the place!!
