The Prophecy is a bit of an anomoly in the Mizuno line with its engineered full suspension system. The midsole of round 2 continues largely unchanged (a Mizuno characteristic - slow change is good), a thin ribbon of foam under the foot with a full-length variation of their Infinity Wave plate providing a shock absorbing suspension system.

The Creation has represented the Mizuno approach to high-end neutral cushioning. The evolution, often cautiously gradual, is true with the sole units, but the upper design and materials is visibly changed.

The Trance has represented the epitome of Brooks' technology, performance, and comfort. Round 13 continues the reputation by maintaining the best aspects of the previous rounds, while nudging updates to key features.

The Cadence bridges the gap between Brooks' slightest and most engineered shoes. The upper has undergone a transformation, adopting an asymmetrical lacing setup, and a tongue which opens on the medial side only - wrapping the foot snugly without compromising the fit.
