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. Get the most out of your performance with these spikes!
