Sole

The Phylon foam midsole provides light, responsive cushioning. There is extra cushioning at the midfoot and heel for a good balance between comfort and protection. This is important on longer distances and provides a smooth, springy transition between steps. The outsole has four replaceable spike tips made of durable steel on a Pebax® plate. The plate is a generative design (created using AI) that recognizes zones that need to be stiff and flexible. This plate, as it were, propels you forward while running and creates a powerful push-off. The spike tips give you excellent grip on all surfaces.

Upper

Ja Fly's mesh upper keeps the shoe breathable and comfortable during matches. Boost your performance with these spikes!
