The toe and side panels are combined to produce further color blocking, and the heel pull button has been removed from the ankle hole rather than looping behind it. The shoe, which served as an inspiration for the Ultraboost Mid, has a mid-top design with Solar Yellow Primeknit, a white Three-Stripes logo, a High Res Blue ribbed collar, and mismatched navy and gray overlays. In addition to providing cushioning, the full-length Boost midsole also promotes stability, thanks to an exterior heel counter.
Our experts say one of the standout features of the Ultra Boost Mid Prototype is its mid-top design, which offers additional ankle support and protection compared to the low-top version. This adidas Ultra Boost Mid Prototype was released on May 5th, 2018, and retailed at $220.
