@manofmany: The Adizero Gear Shift is a new concept shoe featuring a tunable plate that lets runners toggle between a softer or firmer ride mid-stride. Designed to combat mechanical fatigue during ultra-endurance efforts, the Gear Shift comes in two prototypes: - Manual Shift: Physical switch allowing athletes to adjust plate stiffness on the fly as their legs degrade late in a race. - Digital Shift: Smart variant that syncs directly with a GPS watch, allowing runners to pre-program plate stiffness to automatically adjust at mile markers. We're officially entering the era of programmable footwear. Video shot by @manofmany Thanks to @adidasau @adidas @adidasrunning #adizero #gearshift #runningshoes #runningtech #ultrarunning
