The Zeal forges into new territory with its midsole construction. It provides a gentle yet firm heel grip, and the midsole reinforcement provides serious protection over turbulent terrain whilst still being relatively soft. The upper materials are extremely durable and are made from non-absorbing materials resulting in minimal water pickup. With the low profile (6mm drop) the ground control is remarkable. The Zeals outsole RB9X® gives you outstanding traction on both wet and dry surfaces, without compromising durability.
