PB is running shorthand for personal best, and adidas used it on the version of the UltraBoost aimed at faster running rather than everyday wear. This women's pair keeps the palette tight: Core Black through the upper, Cloud White breaking it at the sole and branding, and Signal Coral, a warm pink-orange, supplying the one bright note. Nothing else on the shoe distracts from that single accent.
The running hardware is the line's constant. A full-length Boost midsole carries the thermoplastic polyurethane pellets adidas developed with the German chemical maker BASF, fused under steam into a foam that returns energy rather than absorbing it, and first used in the brand's running shoes in 2013. The PB versions are built to trim weight while keeping that foam intact, which is what separates them from the heavier lifestyle builds the line is better known for.
