The Row’s Signum sandals are the understated and under-the-radar designer shoes owned by people with cool style in 2025. With their simple T-strap design, wide leather band, four-inch block heel, and buttery-soft leather, they embody the refined, exclusive elegance that defines The Row—emphasis on exclusive. These sandals are notoriously hard to find, with only a few sizes sporadically available at select retailers, and unfortunately, none are in my size. So my quest began: find an alternative that has the same look without the $1300 price tag.
Enter Source Unknown’s Thong Heeled Mules—an incredibly similar alt to the Signum sandals I stumbled upon last week. Made from a smooth faux leather, they feature a wide upper strap, a sleek 3.5-inch heel, and the same clean, architectural silhouette. Just like the original, they’re endlessly versatile. Whether styled with wide-leg tailored pants and a crisp button-down, baggy jeans and a tee, or an LBD, these sandals deliver that same elevated, effortlessly chic vibe.
As with many of Source Unknown’s most-wanted items, these won’t stay in stock for long. If you’re thinking of grabbing a pair, keep scrolling, and don’t wait. I’ve also rounded up a few other similar options in case something else speaks to your style. Just a heads-up: The shoes run small, so the brand recommends sizing up by a half size.
