These sandals didn't fit small on my feet: in fact, my normal size 7.5 was too large!
I have somewhat narrow/skinny feet and although, they fit fairly well lengthwise, but still a little bit long, the straps and ankle portion were too loose to provide any stability.
The soles are hard, but moderately shaped to conform to the foot.
I probably would have loved these if they would have fit. !/2 size smaller would probably be too short.
