adidas Ultra Boost 4.0 Grey Three Men。The adidas Ultra Boost 3.0 Grey Four Trace Pink is a running shoe released by adidas as part of the Ultra Boost line, which is renowned for its combination of comfort features with sleek aesthetics. The shoes have a grey upper with pink accents. It is made from adidas’ proprietary PrimeKnit material, which is the preferred option because it is lightweight and breathable, making the shoes comfortable runners. The grey upper is contrasted by a white midsole made using Boost foam, and a dark grey outsole made from continental rubber. Branding elements on the shoe include the iconic 3-Stripes on the TPU cage, Ultra Boost branding on the heel counter, and an Adidas logo on the tongue. What we love about the Adidas Ultra Boost 3.0 Grey Four Trace Pink is the TPU cage that wraps around the midfoot to provide extra support and stability during running. The shoes were initially released on Preowned in great condition- there is some tar? on the soles that I couldn\'t remove. Other than that the shoes look great.
