Kate Middleton pictured in Nike runners and you just KNOW they’ll sell out

Not just any Nikes though, a super expensive pair.

Duchess Kate attended Bond Primary School in Mitcham yesterday to hang out with some the young pupils and see the work carried out by the Wimbledon Junior Tennis Initiative. Kate, who's expecting her third child in April, sported a casual yet chic look for her second public engagement of the day and we're loving her Nike runners. The 36-year-old is clearly a fan of the Nike Air VaporMax style as she was previously spotted wearing the exact same pair in October. Kate's runners can currently be purchased for €210 from Lifestyle Sports which is a pretty hefty price for a pair of trainers. Not only that, the Duchess is clearly thrifty when it comes to activewear for she also wore the same tracksuit bottoms for yesterday's visit. Of course, they're not just any tracksuits bottoms either, these are the Montreal  Tuxedo Track Pant Black and you're looking at about €300 for a pair...we might just stick with Penneys. What do you think, are you a fan of Kate's sporty style?
