Boston 13: Lightweight performance and elite traction for every session Designed for runners who intensely prepare for race day, the adidas Adizero Boston 13 offer a perfect balance between lightness, propulsion, and support. Their technical design allows you to maintain high paces without sacrificing comfort. Cushioning and energy return The midsole combines Lightstrike and Lightstrike Pro foams with fiberglass ENERGYRODS 2.0, providing a smooth yet highly reactive stride that reduces energy loss over long distances. Fit and breathability The extremely lightweight mesh upper offers support and ventilation, while the lacing system ensures a firm fit at the midfoot, maintaining stability at all times. Superior traction The Lighttraxion outsole reduces the overall weight of the shoe without compromising traction, while the Continental rubber in the forefoot enhances the final push-off from the ground. Environmental commitment This model contains recycled materials, aligning with adidas' efforts to reduce its ecological footprint without compromising performance.
