AdidasAdizero Boston 12

Verdict

The Adidas Adizero Boston 12 is a high-performing option in its class — a speed trainer scoring 88/100 in SoleHunt's data-driven evaluation, drawing on 0 consumer reviews and 0 independent expert tests. Tipping the scales at 228g, it is notably lightweight for a speed trainer. The 35mm heel stack — a generous stack — delivers a comfortably cushioned ride at 26 HC, returning 72% of impact energy and feeling exceptionally bouncy underfoot. Geometrically, the Adizero Boston 12 runs on a low 6mm drop that suits midfoot and forefoot strikers, with a 29mm forefoot stack that creates a naturally ground-hugging feel. Fit-wise, the toebox measures 92mm — medium-width, comfortable for most foot shapes — and the upper comes in a standard width. Run true to size. Snug midfoot. It is designed for half marathon, 10k, tempo training, daily training, and performs less well for max cushion seekers or wide feet.
