Thanks to the anonymous emailer who suggested these heels from Davis Shoes. The technologically advanced 'Zoom' shoe has a heel made from carbon fibre, making it stronger than steel, but much lighter. The shoes are topped off with an heel base, a glow-in-the-dark insole and rubber straps across the foot. They come in metallic crackled kidskin, or black for the more reserved! Geek chic will set you back $400!
