In addition to its clean, simple Danish design, this shoe also has ECCO Tri-Fi-Grip®. With three different zones – one for stability, another for durability and the third for rotation – that innovative outsole assists you through your swing, while it is comfortable and flexible when walking. This is also a shoe that will have you walking more naturally, and with greater power and efficiency, thanks to BIOM® NATURAL MOTION®, with that same technology also boosting feeling and stability. Yak leather improves breathability and durability, while the GORE-TEX® construction ensures the shoe is 100 percent waterproof. With the Boa® closure system, you can be sure of a snug fit, with the ability to make easy adjustments.
