Saint Laurent knows how to make a killer shoe. The release of their patent black stilettos with 'YSL' as the heel made modern day Carrie Bradshaw's hearts skip a beat.  For their latest shoe however, we didn't think they'd take the phrase 'killer' quite so literally. The Parisian house has released a stiletto that doubles up as roller-skates; the perfect accessory to fly you from meeting to meeting throughout the day, before your roller derby at 9pm. While obviously this beautiful construction could not necessarily kill you, after a few G&T's, we're guessing they could definitely do some damage.

If your current shoe collection is low on the wheel front, the fun shoes are available in store for a cool AUD $3000. If you're not feeling game, the French fashion house also has a beginner-friendly pair for you to practise with.
