What's better than sequin sneakers? Double-sided sequin sneakers. And they can be yours, thanks to Vans, who have released their Sequin Classic Slip-On Sneakers on Free People.

What better for the holiday season, when you want to add a little festive sparkle but also need to max out the comfort factor?

The Sequin Classic Slip On Sneaker comes in two colorways, Checkerboard/Black and Checkerboard/White, and will set you back $70.

Like all Vans Slip On designs, the shoe has a padded collar and footbed, elastic side accents, the signature waffle outsole and an elevated platform sole. They come in unisex sizes.

The black and white checkerboard is classic and will go with everything!

If you're not familiar with the concept of double-sided sequins (um, where have you been?), it's pretty simple. When you swipe the sequins in different directions, you change the color and pattern of the shoes.

Basically, you're getting two different shoe looks for the price of one. Or three, if you like to rock a mismatching pair.

By the way, this is a special design (like the previous "Nightmare Before Christmas" collection), so it won't be on sale forever. Best snap up a pair of the sequin beauties before it's too late.

Checkerboard/White is actually pink and white. TBH, we want both.

While you're feeling the Vans love, note that yesterday, November 21, was "Checkerboard Day." According to the shoe giant's website, this annual event is designed to help Vans fans come together to celebrate creative expression and giving back.

On Checkerboard Day, Vans donates $1 million of their global sales to imagination.org, a non-profit that "finds, fosters and funds creativity and entrepreneurship in children around the world."

"Help us celebrate!" the website says. "We want everyone to get out, get creative, and get involved in their communities."
