I have other FitFlop sandals, but the bronze vinyl here is very stiff and was so sharp that I couldn't wear them.  They rub between the toes with a harsh stiffness.  I tried to use the silicon thong covers to protect my toes because I like the looks, but they fell off within a few steps.  I ended up with blisters between my toes, which is a very painful matter.  It also rubbed on the top of my second toe and abraded that area.  Find another model.
