Can You Spot The Difference Between Princess Kate\'s Two Pairs of Red Shoes?

We know Princess Kate loves her wedges. And her nude heels. And she

loves her favorite 12-year-old boots. But on the current royal tour of Canada, she\'s showing love for a new shoe hue: red.

Arriving in Vancouver via seaplane on Sunday, Kate accessorized a red-and-white print Alexander McQueen dress with a red clutch from Miu Miu and new red suede shoes – the Russell and Bromley pinpoint court shoe. Retailing for approximately $215, the elegant stiletto with a three-inch heel is now on a four-week wait list, thanks to the ever-present "Kate Effect."

The following evening, Kate appeared to rewear the same heels for a formal reception, where she dazzled in a stunning red dress from British brand Preen by Thornton Bregazzi. But eagle-eyed fashion watchers noticed subtle differences in the heel height and sole color.

In fact, the second pair were actually from the Italian shoe brand Gianvito Rossi – red versions of the nude pump that Kate wore for the family\'s arrival in Canada on Saturday.

With a heel height of four inches, the Rossi design is a little higher than the Russell & Bromley\'s, and rather than a nude sole with a dark trim, the Rossi soles are completely nude in color. But the biggest difference is the price: the Rossis retail for $675.

And Kate isn\'t the only one feeling suede on this tour. Prince William has been wearing his go-to casual suede boots in blue (he also has a similar design in brown) as part of his new, more contemporary look.
