Patented OutDry waterproof-breathable technology provides the most flexible and lightweight protection available to keep runners comfortable in all conditions.

Traditional bootie construction allows water and debris to become trapped between the outer material and inner bootie. With OutDry, the membrane is bonded directly to the outer material. There is no hollow space for water and debris to gather so shoes remain lightweight in all conditions.

The Benefits of OutDry

1. True Fit
Dynamic, four-way stretch, waterproof barrier has no folds, no seams and no seam-sealing tape so you get a consistent and true fit in every shoe.

2. Lightweight
Waterproof membrane is heat sealed to the upper resulting in Zero Water Penetration and no additional weight in wet conditions.

3. Dynamic Flexibility
The patented construction technique of OutDry eliminates the need for materials that inhibit forefoot flexibility. The result is truly waterproof shoes that maintain the flexibility found in non-waterproof styles.
