A low, slender shoe heel.
A kitten heel combines a low profile with a slender, tapering shape. Its identity depends on both proportions, so heel height alone does not establish the category. Christian Louboutin describes the Miss Z Sling Back as having a 60 mm kitten heel, providing a named example rather than a universal height limit. The V&A also records Rayne’s Dubarry slingback from the 1960s with a kitten heel. The narrow shape helps distinguish this style from a broad low heel. It describes the heel itself and can appear on different shoe uppers.
