I may have to keep me a pair of these! These are a low wedge sandal, I feel like they look kind of like a Birkenstock with a wedge. They are vegan leather and super comfortable.
I think these run true to size/half a size small. You could go with either. I am normally a true 6.5. I could wear the 6.5 or 7 in these. I decided to go with my true 6.5 size in case they stretch out.
