I wear shoes now almost 1.5 years old - daily as work shoes at the building !!! Very light, robust, stable sole mega no cracks or abrasions - although only stuck !!! Already umpteen times in the wash at 30 degrees in the washing machine !!! Just great !!! The only downer: After about 1 year, at the right shoe forward a cross-seam is open. It comes as no sew towards the - but superglue does it well.
