The Primeknit upper has been made in part with recycled Parley Ocean Plastic, the adidas Terrex Two Ultra Primeblue Shoes and feature a lightweight textile mesh that snuggly wraps your foot for a comfortable, secure and supportive fit while seamless zones provide comfortable distraction-free movement. The breathable design allows air to circulate and disperse heat on hot runs, while abrasion-resistant weldings keep the shoe protected from trail debris. A high rebound Boost midsole delivers cushioning and energy return with each stride to keep you going over long distances and finally, the Continental™ Rubber outsole is durable and ensures multi-surface grip.
