The Rigi 19 Aqua is an improvement on the universally popular Rigi Aqua style. The difference: the Rigi 19 Aqua style appears on the newly developed “Strato Outdoor” sole. The improved shape of the sole gives it a far more pleasant feeling when walking and greatly improves roll-through in the shoe. The high shaft effectively supports the ankle. The upper of the Rigi 19 Aqua is made of durable, water-repellent leather and fabric.
