The UltraBoost Mid ‘Prototype’ gives nod to all the adidas silhouettes that never made it into production. The mid-top features a Solar Yellow Primeknit upper with navy and grey overlays, High Res Blue ribbed collar, and white Three-Stripes branding. Completing the look are a full-length Boost midsole and stabilizing heel counter.
For sneakers, you may cancel your order within 3 hours of placing it or before it is confirmed by the seller - whichever comes first.

If neither have occurred, you can cancel your order first by accessing it via “Track My Order” or “My Account,” clicking “Cancel Order” and following the instructions.
