The BIOM Terrain allows you to experience the sensation of the outdoors in every step whilst still providing the necessary support for the toughest terrain. The rugged rubber outsole provides aggressive traction while the external flexible heel counter offers extensive support so there are no limits on even the most uneven surfaces. Anatomical fit with forefoot flex for full-on comfort. 3 layer Cambrelle insole for maximum moisture absorption. GORE-TEX 100% waterproof lining keeps feet cozy and completely dry. Performance textile design with sports styling makes it a good choice to have. Conventional shoes fit across your feet at the toes, restricting the way your toes spread as you walk. ECCO’s Freedom Fit is different; it offers a roomy toe box and fits more narrowly from heel to instep, suitable for most widths. Toes spread naturally to support your weight and foster a more comfortable walking experience. Feet of nearly all widths feel good in ECCO, comfort straight from the box.
