The adidas Yeezy Boost 380 “Onyx Reflective” is the reflective variant of the sleek colorway released in November 2020. Appearing just like the standard “Onyx” 380 at first, the difference is revealed when the shoes are hit with light in the dark and the reflective threading in the Primeknit flashes. The upper is featured in a blend of black and dark grey Primeknit in an intricate pattern. The rest of the shoe matches the stealthy appearance of the body with black laces and a smoky black translucent rubber midsole that houses the full-length Boost foam cushioning. The reflective “Oynx” 380 released in significantly smaller quantities than the standard “Onyx” edition. Release date: November 27, 2020

HOW TO MEASURE
In order to select the correct shoe size, we recommend you measure your feet using the following guidelines.

Wear the kind of socks or tights you would normally wear with this type of shoe.
Stand up straight on a flat surface with your heel against a wall. If necessary, ask someone else to help you take the measurements.
Measure from the base of your heel, keeping it pressed against the wall, to the tip of your longest toe.
Always measure both feet and use your longest foot as your benchmark.
