Pinches across the joint of the big toe (bunion area) and crunches in the little toe too.  Furthermore, the over-the-arch strap cannot be tucked behind your heel. I found the cleo ii version to be much more comfortable - the arch strap can to slipped behind your heel to hold your foot in place or can tucked down behind the back of the sandal, making the cleo ii into a slide.  No bunion or little toe issues.
