UltraBoost has proven to be an effective adidas franchise, and the UltraBoost ST range is the most versatile in the lineup. The update to this cushy high mileage shoe is focused on maintaining its greatest strengths without messing with things.

The midsole is Ultra Boost foam, with it’s bouncy well-cushioned feel, and a thermoplastic medial sidewall keeps the foot lined up while shoring the Boost pellets effectively. The outersole is stretch web Continental rubber, with good durability but light in weight. The result is a well cushioned, stable high milage shoe for daily training.
