About this product
The adidas Ultra Boost Uncaged Black Grey Three is a variation of adidas’ Ultra Boost line of running shoes built without the "3-Stripes" logo midcage. With a grey and black colorway and a white midsole, its upper is constructed from Primeknit, its outsole from rubber, and full-length Boost technology runs in the midsole. The adidas Ultra Boost Uncaged Black Grey Three is noteworthy for being the first Ultra Boost sneaker adidas released without the cage, giving the sneakers a sock-like fit. A sock-like collar around the upper completes the snug and comfortable fit, while black plastic along the heel ensures the shoes contour to the foot to deliver ultimate performance. What our experts like most about the adidas Ultra Boost Uncaged Black Grey Three is its ultra-comfortable fit and performance capabilities. Originally released on June 7, 2017, the sneakers sold for a retail price of $180.
