The adidas Ultra Boost ST is a plush road shoe designed to givea very smooth ride at high speeds or over long distances. In use they feel great, with a soft but supportive upper and a good fit, and they look smart as well. Although designed for road use, the sole unit performs well on well-maintained trails, but with its high stack height and cushioning, it’s less suitable for rough ground. The Continental rubber sole grips in both wet and dry conditions, and lasts well. The ST is the stability model with medial support, however, the Ultra Boost is also available as a neutral shoe. Both have an 8mm drop.
A plush road shoe that’s great for training on the trails.
