The Ecco Chiltern Gore-tex shoes incorporate Gore-tex technology. The smooth and oiled nubuck leather uppers and the Gore-tex membrane ensure that the shoes are 100% waterproof and breathable. The textile linings are highly moisture absorbent and breathable while the removable leather inlay soles use Eccos Comfort Fibre system to ensure an anti-bacterial and cool environment inside the shoes. The shoes are suitable for orthotic insole users. They are complete with PU/TPU outsoles to be light, flexible and hard wearing with a shock point for additional shock absorption.
