Our Verdict
HOKA Mach X
adidas Adizero Boston 12
The adidas Adizero Boston 12 and HOKA Mach X are both super trainers designed to provide support for everyday runs. The adidas offers superior stability. However, it's less cushioned but still heavier, making it feel harsher and less agile. This means the HOKA is more versatile and more comfortable for most runners, especially over longer distances or varied training efforts.
