Admittedly they weren’t the most suitable footwear.

Still, the Duchess of Cambridge didn’t let a pair of towering wedges put her off trying her hand at a game of volleyball today.

Dressed in a pair of skintight ‘jeggings’ by J Brand, a Ralph Lauren breton-style top, a one-button blazer by Smythe, £695 diamond earrings by Kiki McDonough and, of course, those Stuart Weitzman for Russell and Bromley ‘corkswoon’ wedges, Kate gamely stood at the net and slammed back a few decidedly passable shots.

The Duchess of Cambridge played volleyball today as she took part in a SportsAid workshop at the former site of the Olympic Park in London.

That said, the sporty Duchess missed what one onlooker described an ‘absolute sitter’, as she wasn’t able to jump up high enough in the five inch heels.

Kate was taking part in a sports workshop at the Queen Elizabeth Olympic Park in East London run  by SportsAid, a charity which supports young athletes at the start of their careers.

The Duchess became patron of the organisation last year and was, said aides, keen to meet the athletes it was helping face-to-face and get a ‘detailed insight into the challenges they face’.

It was Kate’s first solo public engagement since the birth of her baby son Prince George.

It is believed that she left her three-month-old son at home in Kensington Palace with her husband, Prince William.

Despite sporting a pair of Russell and Bromley blue heels and skinny ‘jeggings’ she managed a few quite passable shots and at one point she leapt up to score a ‘spike’

The Duchess’s Russell & Bromley wedges may have hindered her game however as one bystander claimed she missed a ‘sitter’

On her arrival she was greeted by Tim Lawler, chief executive of SportsAid, who then introduced her to a selection of its trustees.

Then it was straight down into the Copper Box arena where she began by chatting to a group of young badminton players with whom she had been expected to have a game.

Disappointingly she declined, but told them she had tried her hand at the sport before.

Eliza Cottingham, 17, said: ‘We had been told she would have a game with us, but she didn’t. She said she had played before as she wanted to try and see whether it was like tennis, but she said she found it much harder.’

At the wheelchair volleyball the Duchess chatted at length with Ade Adepitan MBE, himself a bronze medallist the Athens 2004 Paralympic Games.

The sportsman said: ‘She was very keen to learn more about the difference SportsAid meant to these young players and asked whether we had any more players coming through as a result of last year’s games. I told her we had more than ever before, it’s been remarkable.

‘It’s a shame she didn’t join us as its one of the few sports that able bodied and disabled can play together. I think she’d be great – she’s got the height and is very naturally athletic. But she said she had only ever played netball at school.’

Kate, 31, left her three-month-old son with her husband to attend the event at the Queen Elizabeth Olympic Park
