These are better than the sabas in terms of fit and squishy bottoms, but still not quite as good as the older sabadellas.  The shiny ones are also a little weird, they have places that are almost quilted along the sides, where the summer models have mesh.
they do the same thing that every pair of puma ballet flats does to me, where they rub my heels raw until they break in --  no worse or better than any pair of sabas, sabadellas, or esperas.
the addition of breathing holes in the side of the shoes is nice though.
