I have over 15 pairs of Ecco shoes, golf, dress and casual. I have recently has three pairs of my men’s dress shoes have their soles deteriorated and crumble off. These shoes were 4-5 years old but like brand new. As I am retired they were worn very little throughout COVID. When I contacted Ecco they would not stand behind their product and stated it did not fall within their warranty criteria. I am no longer a Ecco customer. This is a common issue with their shoes. Please do your research before buying their dress shoes with a light weight sole. I am truly disappointed with Ecco. Long time, loyal customer. Dave
