Heidi Klum Pairs Sculptural Maticevski Dress With Iconic Casadei Blade Boots

At the 2022 Billboard Music Awards in Las Vegas, Heidi Klum opted for a high-contrast aesthetic, pairing architectural evening wear with edgy footwear.

Joining DJ Khaled at the MGM Grand Garden Arena to present the Top Rock Artist award, the AGT judge wore a pastel yellow gown by Toni Maticevski, a Melbourne-based designer recognized for sculptural silhouettes.

Selected by stylists Rob Zangardi and Mariel Haenn, the “Nightshift” strapless dress features a structured bodice and asymmetric draping.

The design’s thigh-high slit served as a showcase for Klum’s choice of footwear, effectively bridging the gap between a classic gala look and a more modern, editorial style.

The iconic model sharpened the look with black opera gloves, echoing the inky finish of her Casadei “Blade” thigh-high boots—an instantly recognizable silhouette that goes far beyond a standard stiletto.

Introduced in 2011 by Cesare Casadei, the Blade was conceived as a “logo-less” signature: a heel so distinctive it could be identified purely by its razor-thin profile.

Engineered from hardened stainless steel after months of development with aerospace specialists, the heel achieves its knife-like precision without sacrificing structural integrity.

That sharp, flat-edged geometry catches the light with every step, creating a striking visual line that elongates the leg far more dramatically than a traditional rounded heel. In boot form—especially with an over-the-knee shaft and a thigh-high slit—the effect is amplified, turning Klum’s stride into a study in contrast: soft draping above, surgical precision below.

Her boots are made of black suede and feature an over-the-knee shaft, pointed toes, and 4.3-inch Blade stiletto heels.

For her beauty look, she parted her signature blonde hair in the middle and wore fake lashes, smoky eyes, and pink lipstick. The German model was joined on the red carpet by her husband, Tom Kaulitz, who’s 16 years her junior.

The Tokio Hotel guitarist matched his wife in an all-black outfit, including a long-sleeved sweater, belted black trousers, and black loafers with white midsoles.

He wore his signature beard, swept his long, wavy hair to the side, and completed his look with gold bracelets.

From Razor-Sharp Heels to Red-Carpet Power Moves: Why Casadei Boots Still Dominate

Heidi Klum’s Blade-heeled boots aren’t just a finishing touch—they’re part of a larger legacy that continues to shape how celebrities approach statement footwear.

From sculptural over-the-knee silhouettes to bold platform styles, Casadei has built a reputation for turning boots into focal points rather than afterthoughts.

If Klum’s look highlights the brand’s precision and leg-lengthening impact, these standout moments show just how versatile—and enduring—that appeal really is.
