Camilla Parker Bowles attended Wimbledon wearing a bunion-friendly footwear.

According to Carly Read, a journalist for Daily Express, Camilla watched the tennis tournament without Prince Charles and wore a block heel by Sole Bliss. The Duchess of Cornwall's footwear during the sighting was designed for a wide-footed woman. It also features a cushion inside to soothe the bony bump caused by poorly-fitting shoes and constant wearing of high-heels.

This is not the first time that Camilla has worn the footwear. According to the company's spokesperson, the royal also wore the same heels when she visited Wales with Prince Charles a few weeks ago.

"She wore them on a royal trip to Northern Ireland and on another in Wales recently," the Sole Bliss company rep said.

The women of the royal family have different approaches when it comes to making their feet comfortable in heels all day. Meghan Markle has been seen wearing oversized shoes on multiple occasions. According to a fashion expert, a number of celebrities, including the Duchess of Sussex, do this to avoid blisters.

"Celebs often go a size up, or even two, in the shoe department when they're at an event or on the red carpet and it's for one reason we can all relate to - to avoid blisters," Harriet Davey said.

"There's nothing worse than uncomfortable shoes (we've all been there on a night out) and when celebs like Meghan are wearing heels for a long period of time their feet can often swell up," the expert continued. "The swelling can cause blisters and in the long run bunions — like long-time heel fan Victoria Beckham has been rumored to suffer with."

Just like Camilla and Markle, Kate Middleton has her own secret to make wearing heels all day comfortable. The Duchess of Cambridge uses Alice Bow's leather insoles. The product combines fashion and comfort. It also provides solutions to "ugly and ineffective insoles" so women can enjoy their footwear.

In related news, according to a report, Prince Charles didn't marry Camilla before Princess Diana because she was perceived as an "experienced" woman. In addition, the Duchess wasn't "aristocratic" enough for the next-in-line to the throne.
