Query: Not so great

The general quality of this product is O.K. and I've no complaints over the material construction, excepting that they don't fit my feet as well as normal flip-flops. The soles are flat and stiff, without give. I feel that even a minimum amount of bend works better with my stride. I'm willing to concede that they may feel better after being broken in, when the flat begins to sink and mold to my heels and toes, but as low traffic house slip-on's, that could be a while. This stiffness is what Zori's essentially are; as a matter of preference, I'll stick to normal flops.
