The latest entry in the series, the New Balance Women's Fresh Foam X 860v13 Running Shoes feature a structured and breathable engineered mesh upper. This allows your feet to breathe and provides a secure fit alongside an internal gusseted tongue, snug heel cap and traditional lacing system. The upper works in synergy with the updated midsole construction that combines dual-layer Fresh Foam X foam with a medial post to promote a smooth and stable ride that's both comfortable and responsive. The midsole contains bio-based content made from renewable resources to help reduce New Balance's carbon footprint. Finished with a durable rubber outsole for a long-lasting reliable grip and reflective detailing to enhance your visibility when running in low light.
