Amazon Prime Day is over, but Princess Kate's favorite Superga sneakers under $100 are still on sale!

Princess Katherine and I don't have much in common. Princess Kate and I have been wearing sneakers for about the same period of time (since the mid-2010s) and still do. Here's the good news: our longtime favorite pair of white Supergas are discounted on one of the best sneaker specials of Prime Great Price Day, ringing up cheaper.

Originally retailing for $70, they are on sale for $47 as part of Amazon Prime Big Deal Day (otherwise known as October Prime Day). The discount only ran on October 8 and October 9, but her kicks are still heavily discounted. However, the official sale is technically over, so there is no telling when these deals will end, so act quickly if you want to get a pair for less.

Kate Middleton owns several pairs of Superga 2750 Cotu Classic sneakers, but her most worn pair come in classic white. The royal's versatile kicks are trademarked for their all-over canvas fabric and sporty, rounded silhouette.

Middleton's decade-long love affair with Superga sneakers should come as no surprise, however. She had her best fashion moments when wearing sneakers. And since the Duchess has been known to wear the same accessories repeatedly over the years, you won't see her wearing affordable, trendy sneakers more than a dozen times."

She has worn the Longchamp Le Pliage tote bag, a favorite since 2005, and the 2011 The same is true of her Longchamp Le Pliage tote bag, which she has worn since 2005, and her Aquazzura pointed-toe pumps (also worn by sister-in-law Meghan Markle), which she has worn countless times since her marriage to Prince William in 2011.

Superga splendor runs in the family, and Kate is not the first royal to give the fashionable seal of approval. Princess Diana wore navy blue sneakers from the line nearly 30 years ago; in 1997, she paired them with light-wash jeans and a black blazer at Angola.

I also personally adore 2750 Cotu Classics. Not only did I wear the lacy white shoes to a wedding reception this summer, but I have owned over 15 different pairs in the last 10 years. In fact, I collected them in high school. The rubber soles make them great to wear, the canvas makes them easy to care for, and they never go out of style.

If buying another pair of cool white sneakers isn't on your to-do list this Prime Day, don't worry. Scroll down to see other super sneakers on sale right now. Marked-down shades include the blue pair Princess Di wore and a trendy red version. There's more than one way to dress like fashion royalty with these deals.
