Spanx founder unveils new line of stiletto-heeled sneakers called Sneex

Nearly 25 years after Spanx shapewear took hold of women's silhouettes, its founder has unveiled another first: the stiletto-heeled sneaker.

Sneex, a hybrid stiletto touted on the company's website as a "hy-heel," is the latest invention by entreprenuer Sara Blakely, the woman behind the billion-dollar brand, Spanx, the undergarments worn by the likes of Oprah and Gwyneth Paltrow that took the fashion world by storm in 2000. 

With her latest invention, Blakely has set out to create a luxury high-heeled shoe that's as comfortable as a pair of sneakers, resulting in a bold design that appears to be a literal interpretation of the concept.
