Introduced with a single heel height of 105 millimeters, the style has evolved to include 5 options, the most popular being the original. The wonder of the BB is its versatility: chic perfection with a little black dress, but exhibiting plenty of cool-girl cred when styled with a pair of jeans. Maybe it's the way the BB's perfect pitch repositions a woman's stance, accentuating her curves. Or how the cut of the vamp offers just the right tease of come-hither toe cleavage. I had new soul protectors put on. Add more comfort on the soul.
