They make a quiet squeak with each step, as if the soles are filled with air.  Also, they are plastic like, not fabric and the part where there is stitching pokes my daughter's foot as the stitching is with a clear &#34;fishing line&#34; type thread.  Also, there is a part on the inside where there is a pucker that looks like the point where the liquid is poured into the mold for making the sandals and that pucker also irritates her foot.  We put some tape on to alleviate the problem but when it gets dirty or wet it slides off and pokes her foot again.  She just stopped wearing them after a couple of times-too much trouble.
