Structure 25

With stability where you need it and cushion where you want it, the Structure 25 supports you for long miles, short training runs and even a down-and-back before the day ends. It's the stability you seek, loyal from the first tie-up, tried and tested, with a midfoot system that's fully supportive and with more comfortable cushioning than before.

• We softened the materials on the inside of the heel, collar and tongue, so that any part of the shoe that's touching your ankle feels smooth and comfortable.
• Single-layer mesh provides breathability and durability.
• The durable rubber sole has grooves in the forefoot to create flexibility, and vertical grooves down the side help create stability.
