Positive: They are nice and light. Much lighter than the other sandals I have (Bedrock). They are fairly flexible and fit well on the foot. You can adjust them in different places. However, I would say that the straps should be shorter over the toes, as it is difficult to tighten more because then the strap becomes a bit too long. Negative: I didn't like that they were tight at the little toe. I am used to having a strap between the toes and then the foot is very free. However, I wanted to try a z-sandal as it is nice not to have the strap between the toes sometimes. My little toe couldn't move very much even when I loosened the strap over the toes properly. That's just how the sandal is made. It doesn't seem to be a problem for many, but I have sensitive feet and thought about that strap all the time and felt that if I were to walk far it would start to chafe. That's why I sent them back. I still recommend them because they are good sandals otherwise, and you probably have less sensitive feet than I do.
