The History of Sandal Back Straps And How to Adjust Them

Let’s talk about sandals: those timeless, breezy, open-toe wonders that have accompanied humanity for thousands of years. More specifically, let’s do a deep dive on the not-so-humble back strap. Yes, that extra piece of leather (or synthetic material) behind your heel deserves a spotlight. So strap in and let’s explore how back straps became a staple in sandal design.

Sandals are easily one of the oldest forms of footwear. Civilization after civilization made sandals from available materials—think papyrus in Ancient Egypt, grass in Asia, and leather in Mesopotamia. Early sandals were simple: a flat sole tied to the foot by a thong across the top. They did the job of protecting feet from scorching desert sands or rough terrain. But here’s the thing—those early prototypes often lacked a back strap. They were more like flip-flops in a literal sense, flopping around as people walked.

While these early civilizations deserve respect for making the first documented sandals, the concept of a reliable, heel-encasing back strap wasn’t yet standard. People likely improvised with extra ties and wraps, but the formal “back strap” feature we know today was still in the making.

By the time we get to the Greeks and Romans, things start getting interesting. These cultures refined footwear for different uses—athletics, everyday wear, and warfare. Sandals were especially popular for their practicality in Mediterranean climates.

• Strappy Sandals: The Greeks had various sandal styles with lacing that sometimes wrapped around the ankle, providing an early form of support.

• Custom Fit: Wealthier Greeks might have had sandals made to measure (some things never change!). But a specifically dedicated back strap was still optional—straps could tie around the ankle or crisscross up the calf.

Roman soldiers wore a type of military sandal called caligae. These were sturdy, thick-soled sandals with lacing across the top and often around the heel. You could call that heel wrap a Proto back strap. And for good reason: when you’re marching for miles or fighting in the far reaches of the empire, you don’t want your sandals flying off mid-battle.

This was arguably a turning point: the need for sturdy footwear in battle meant the Romans found that a secure fit around the heel was non-negotiable. Their sandals offered a glimpse of the future, one in which everyday folks might also appreciate the extra stability of a well-fitted back strap.

Fast forward a bit, and sandals in medieval Europe weren’t as common, especially in colder climates. Boots, slippers, and closed shoes took precedence. But in warmer regions like the Middle East, Northern Africa, and parts of Asia, open-toed shoes continued to develop.

It wasn’t until global trade routes expanded that sandals started to become mainstream again, finding new expressions in different cultures. By the late 19th to early 20th century, as fashion became more globally influenced, footwear designers began experimenting with form and function, turning to sandals for both style and breathability.

• Early 20th Century: Modern shoemakers introduced back straps in women’s sandals for style and improved fit.

• Mid-Century: Brands in Europe (especially in countries like Italy and Spain) popularized sandals as refined yet casual footwear. They used buckled back straps for that snug, classy look.

• Late 20th Century: Sport sandal brands jumped on the functional bandwagon, giving us adjustable velcro back straps. Perfect for hikes, kayaking, and everyday casual wear.

Let’s get one thing straight—there’s nothing wrong with a good old-fashioned flip-flop. But that classic flip-flop or thong design can be a little too free-spirited for some feet, leading to extra effort gripping the sole in place. A back strap, however, helps keep everything in line, literally. It might not be the solution to all of life’s problems, but at least it’ll solve your “I keep walking out of my shoe” conundrum.

At Chiappetta Shoes, we love celebrating the tradition and innovation behind all types of footwear, and sandals with back straps offer some of the best solutions for comfort, style, and foot health. After all, your feet do so much for you—why not give them the supportive hug they deserve? Just not too tight! Watch below to learn how to adjust your sandal back straps for a proper foot placement.

Today, back straps show up in every conceivable style: sporty, casual, dressy, bohemian, high fashion—you name it. With ongoing innovations in materials (think eco-friendly cork, recycled plastics, or vegan leathers), these supportive straps aren’t going anywhere. Expect even more comfort technologies (cushioned footbeds, arch support, memory foam) that pair beautifully with a well-placed strap over the heel.

And because sustainability and foot health are increasingly top of mind, we’ll likely see more orthotic-friendly sandals boasting adjustable backstraps. If you ask us, it’s the perfect marriage between style and substance.

From the earliest Egyptian slip-ons to the utilitarian Roman caligae, sandals have come a long way. The back strap’s history is intimately tied to the evolution of humans wanting to walk around without losing their shoes (and without feeling like they’re one gust of wind away from going barefoot). Whether you’re trekking through ancient roads or modern sidewalks, it’s safe to say that the back strap is here to stay.

If you’re looking to find that perfect pair, Chiappetta Shoes has the perfect solution. So next time you slip into a pair of sandals with a back strap, give a little nod to the ages. You’re wearing a piece of world history, updated for the 21st century.
