Don't worry, we're not dissing Katy Perry's latest footwear choice here (although the less said about that outfit, the better): we are simply pointing out that her right foot does not entirely match her left, giving an irregular edge to her rather intriguing take on the sports-luxe trend.

This isn't the first time a celebrity has stepped out in odd shoes, and Helena Bonham Carter rarely wears a pair that match nowadays. But it's the first time we've seen Katy pull this particular footwear stunt. The singing sensation was celebrating her team's win at Super Bowl XLVI at Lucas Oil Stadium, Indiana at the time, so we can probably forgive her the lycra.

Individually, we're big fans of the shoes which are a built-up concealed wedge trainer, similar to those worn by X-Factor honeys Little Mix. They certainly provide a flattering leggy uplift, so it's worth taking not of this style if you're one of those people who'd secretly like to live in trainers but don't like what they do to your ankles.
