The Nike React Element 87 “Neptune Green” is a stylish look for a shoe that has been hailed as the best sneaker debut of 2018. The React Element 87 is known for its futuristic aesthetic, amazing comfort, and limited quantities. This “Neptune Green” colorway kept the silhouette’s momentum strong going into fall, when it released in October. It features a grey shade across the transparent material on the upper, with solid panels in black and navy. The green shade is found on the heel tab and the translucent rubber outsole.
