Kate Middleton Just Wore $50 Sneakers & They’re Not Sold Out…Yet​

Kate Middleton is Olympic ready, and she has the sporty-chic outfit to prove it.

The 38-year-old Duchess of Cambridge reminded us of her athleticism during a visit to the London Stadium at Olympic Park in Stratford today to celebrate the work of her patronage SportsAid and how sports have an impact on young people’s lives.

The mom of three dressed for the occasion, wearing now sold-out emerald green Zara culottes (the Middleton effect strikes again!), a green scoop-neck sweater, a navy blue blazer and vegan Marks & Spencer sneakers ($50) with green accents. The best part? Her tennies are still available.

There’s a reason Middleton swapped out her go-to Superga Cotu sneakers in favor of these Marks & Spencer babies. The green and white ribbon detail lace-up trainers are fitted with Insolia Flex technology, which makes them comfortable for walking, or, in this case, very short distance running. Since they’re vegan and low-cost, they also help further Middleton’s mission about shedding light on sustainable fashion and proving that looking cute doesn’t always have to mean shelling out the big bucks. Still, at this price, we’re guessing her tennis shoes won’t be in stock for long.

In addition to debuting the ultimate casual-cool outfit, the duchess participated in track and field activities, even learning how to use the starting blocks when it came time to run a little track. She also chatted with Olympic champion Jessica Ennis-Hill, whom she first met while acting as an ambassador at the London 2012 Olympics, and reminisced about her days playing hockey, netball and swimming while in school. She even tested out a little Taekwondo, met with young athletes and their families and got a little silly (judging from the photo below).
