Kate modelling for the United Kingdom clothing brand "Really Wild Clothing" during the Game Fair event at Blenheim Palace.
The royal was first spotted in the £475 long tassel boots at the Game Fair at Blenheim Palace in August 2004.
The couple met as first-year students at St Andrews University.
Catherine focuses heavily on children's charities, and is also a patron of the Royal Foundation along with her husband Prince William, and her brother-in-law and sister-in-law Prince Harry and Meghan, the Duchess of Sussex.

A year later, the Duchess rocked the same leather kicks at the Gatcombe Park Festival of British Eventing on August 6, 2005.
The Duchess was dressed down in a khaki green jacket, jeans and boots which is a definite departure from her usual attire for public engagements.
As she toured Paddington recreation ground, Kate laughed and hugged the enthusiastic children. "Hello, what are you doing here?" she asked one small group of kids. "They can spend hours out there", she gushed.
The boots once again made the ideal choice later that year when Kate and William braved the wind and rain on an outing during their royal tour of Canada in September.
Kate's visit ties in with the work she's been doing on children's mental health and the importance of early intervention and support.
