Go wild and go fast in the ECCO BIOM 2.1 X COUNTRY, a sporty new shoe that is perfect for trail running and cross-country adventures. Speed, sublime comfort and high performance are combined in a shoe that is powered by BIOM® NATURAL MOTION® Technology. Three independent layers, and a mix of premium textiles and durable ECCO Yak Leather, are combined to create a lightweight, breathable and comfortable upper. While the PHORENE™ midsole supplies energy return and bounce, the ECCO PERFORMANCE RUBBER+ outsole delivers excellent grip and traction.
