Plastic shoes, sometimes called jellies, started a comeback last year with Marc Jacobs’s reissue of his beloved mouse flat in jelly-bean hues of PVC; this year, Tory Burch’s logo slipper joined in. But for their glossy charm and vibrant color, this pair from Kartell (yes, the furniture company) is this season’s best. In a bold move outside its category, Kartell got Italian designer Norma Luisa to create a small group of jellies called Glue Cinderella ($135 at Kartell, 39 Greene St., nr. Grand St.; 212-966-6665), which come in seven solids, three two-tone colorways, and clear. There are tiny vent holes in the arch, and the heel is star-shaped, so your footprint will be unmistakable.
