Inspired by runners and designed for active kids who want to move in all weathers, the ECCO BIOM K1 sneaker mixes fresh, athletic design with advanced technologies. Premium textiles and leather details enhance the sporty style while the GORE-TEX waterproof construction ensures that kids' feet stay dry and comfortable. ECCO's own BIOM® NATURAL MOTION® technology, which was originally developed for runners, encourages growing feet to move more naturally. With two quick fasteners, the sneaker is easy to adjust, while it is set on a lightweight, flexible and durable PU outsole which offers grip and has flex zones.
