Bought these as a replacement for my previous for a similar pair of sandals which I had for over ten years, and had more than a thousand or more miles of walking on various terrains on them.  These sandals are slightly different in that a piece of material is not included on this model (as are still on the previous pair) yet it has the same model number so I suppose that ECCO took off the piece.  It is not a big deal, yet worth mentioning. An Amazon Prime item.
