Adidas expands their Ultraboost X collection with a tonal rendition for the ladies ($180). This variation is constructed in a full primeknit up with a floating arch at the mid-foot for a unique design. The model also uses a torsion system between the heel and fore foot to provide stability and durability. Lastly the silhouette uses boost technology and a stretch-web continental rubber outsole to balance it out. The color way featured is a primarily nondye white. Purchase your pair online and in store.
