The adidas Terrex Agravic Flow 2 trainers are built with a grippy Continental rubber outsole and a versatile tread that feels soft on the streets, but really shines in the mountains. Lightweight EVA cushioning provides comfort and stability underfoot. The mesh upper is breathable, supportive and durable enough for rugged trails. The upper of this shoe is made from a high-performance yarn containing at least 50% Parley Ocean plastic. The other 50% of the thread is recycled polyester.
