I ordered a handful of items during the Zara sale a few weeks back (still ongoing, but selection is probably better in stores now from returns). The only item that I loved enough to keep? This pair of black ballerina flats with beaded straps (coincidentally, a friend also bought and kept! Great minds especially since we didn't coordinate beforehand).

I was afraid the flats may be too big, but Kefee heel inserts to the rescue once again. Since my initial post about them, I do think the heel inserts work much better than the toe inserts. With more weight pressing down on the toe inserts, they seem to lose their cushion fairly fast.
