The Nike LeBron 20 UNKNWN Message in a Bottle was a collaborative effort put together by Nike and UNKNWN, the sneaker boutique that LeBron James first founded in 2019. This Nike x UNKNWN LeBron 20 had an upper constructed out of a light grey suede material along with a light blue mesh and some leather worked into the mix for good measure. This sneaker also featured everything from exposed stitching on the main Swooshes to glow-in-the-dark touches on the TPU Swooshes placed over the top of them. Additionally, it had speckling on the midsoles and outsoles that were translucent. But our favorite aspect of this LeBron 20 was the co-branding found on the tongues. It helped celebrate both of LeBron's main sneaker-related endeavors in the same place. The Nike LeBron 20 UNKNWN Message in a Bottle was first released on June 22, 2023, and it carried a retail price of $210.
