These sandals are super comfortable, the material is so great that your feet just form fit into the shoe. I've been a Soda customer for over a decade, and this is the first time I've had a problem with my shoe. I wore them three times before I noticed the material that holds your foot in the shoe beginning to fray (see attached photo). I was super disappointed, but I'm still wearing them. I love the shoes so I'll continue to wear them until I cannot!
