I bought them on December 17, 2017. I wear them from time to time when I change shoes and use many pairs of shoes all the time. Today I noticed that the sole of the model on the right was torn from side to side. .Because I can only wear these shoes 3-4 days a month, I wear them 30-40 days. So compared to the Cole Haan brand, this is definitely not what I expected or experienced from this brand.
