The adidas PureBoost, which was launched in May 2014, revolutionized the industry with its pioneering full-length Boost midsole. This particular edition, named 'Tech Grey', boasts a lightweight fabric upper and a perforated heel cup that not only promote breathability but also allow for flexible movement. Additionally, the Boost technology embedded in the midsole provides exceptional energy return for a heightened performance experience. The shoe's design is characterized by a tasteful and understated monochrome grey color scheme, complemented by the iconic Three-Stripes branding along the midfoot. To ensure durability, the shoe features an additional layer at the toe and a lace guard.
