Balenciaga doesn’t stop  in the past day alone, it has revealed its latest Justin Bieber campaign, a Valentine’s Day capsule, and opened pre-orders for the upcoming Defender sneaker, and now it returns with yet another Spring/Summer 2022 runway offering: the Ultra Flat Mule.

As seen on the SS22 red carpet runway and in the special episode of The Simpsons, these Demna-designed mules are definitely one of Balenciaga’s most intriguing silhouettes to date. In recent seasons, the brand has been playing with ergonomics and orthopedic styles, frequently referencing the human foot in its footwear designs, releasing everything from the Space Shoe to the Toe Bootie and other Vibram-associated styles.

For the Ultra Flat Mule, Balenciaga crafts a slim-fitting sock-like structure from thermoplastic polyurethane that’s been covered in a thin carbon fiber weave exterior layer that makes for a light, second-skin shoe. The bottom of the shoe is completely flat, while at the toe you’ll find, well, toes.
