Caitlyn Jenner certainly knows how to make Khloe Kardashian envious!

The former Olympian has been rapidly adding to her shoe collection -- complete with several pairs of head-turning heels.

So, naturally, she tweeted her stepdaughter a peek at her closet, playfully writing, "Giving @khloekardashian a run for her money, dontcha think?"

And even though it's a quick glimpse, we were still able to spot a pair of Valentinos in there!

But it may not be as easy as we think for Caitlyn to find a pair of designer shoes.

Vanity Fair's Fashion and Style Director, Jessica Diehl, revealed to ET that Caitlyn's feet presented a bit of a challenge when she styled her for that famous "Call Me Caitlyn" cover.

"She is so proportionate, and yes, a size 13 shoe, difficult to find," Diehl admitted. "But I think maybe we'll get lucky now and the Paul Andrew and Tabitha Simmons of the world and Manolo Blahnik will suddenly start making size 13s -- you never know."

For now, it looks like she has enough pairs to hold her over!

ET recently spoke with her stylist to find out how Caitlyn picked the perfect Versace gown for the 2015 ESPYs. Watch below.:
