Who They Suit

Comfort, durability and fit determine whether a shoe survives a marathon block. Midsole resilience, rocker geometry and outsole compound all influence how fresh a shoe feels at mile 20. In wet UK conditions, traction and upper security matter as much as cushioning.

Testing Method

We logged 100–150 km in each model, covering easy runs, long runs and marathon-pace workouts. We rated transition smoothness, stability under fatigue, outsole grip in wet UK weather, and cushioning durability on back-to-back long runs.
