Dynamic Fit
Foot support system designed to reduce the space between the foot and the shoe, thereby ensuring excellent comfort.

Nike React
Nike React cushioning provides extraordinary responsiveness. When your foot touches the ground, the foam responds to the impact of your step by returning to its shape. The more energy you put into your step, the greater the energy return will be.

Gore-Tex Invisible Fit
The Gore-Tex lining is directly integrated into the upper to make the shoe as light and flexible as a normal model. This membrane provides lasting waterproofing and increased breathability. Water stays outside and perspiration is wicked away.
