If they last 5 years and then wear out (5 years for me is a lot of use) I would easily buy them again. 5 in Cole Haan) I ordered a 9 in this shoe and it fits perfectly. You wont even notice they are there. There is no spring tension on the rod and it seems to flop about. But it has yet to take over an hour to fully charge. The idea of the storage sounded great, but not needed. I suggest that CAMEL CROWN Mens Hiking Sandals are even nicer and at a price of 30-50% less. only beginning to hear interruption when I was on the entirely other end. Had always gotten Earth Spirit sandals but can no longer find them. We bought these shoes for an event but we used them for a photoshoot and they still look like new (the shoot was in different locations, most of them out in gardens)
