Victoria Beckham’s wildly inappropriate workout shoes

It's no surprise that Victoria Beckham can make even the most ambitious woman look like a total train wreck, but she may have gone just a little too far, this time.

The former Spice Girl-turned fashion designer posted this photo on twitter Wednesday, which shows her working on a laptop while walking on a treadmill -- while wearing dubiously high stiletto boots.

Beckham was in London this week to speak to students at the Condé Nast College of Fashion & Design.

A mother of four, Beckham credits her strict exercise regime for her svelte figure, but we've got to wonder about the state of her feet.

A 2012 study found that wearing heels causes more muscle fatigue and can increase risk of injury -- so while her commitment sure is impressive, we don't recommend following in Beckham's heeled footsteps.
