I got my shoes in April 2021 and hoped for a sustainable alternative. Now, 6 month later I am very disappointed. The shoes are having holes at the sewing (right side were the hard plastic from the front and the soft fabric are sewed together). I contacted the support to get an exchange shoe or some advice for repair, since I thought this has to be a manufacturing error. They told me that the warranty only covers 6 month and offered me 20% off on the next shoes. Not sure what their definition of sustainability is, but shoes that only last 6 month I personally don’t consider good quality or sustainable.
