Women's Heeled Sandals: Heel Height, Straps, Stability

High-heeled sandals are often bought for a specific occasion and then rarely worn again. If the heel is too high, they’ll only last one evening; if the heel is too thin, they’ll get stuck in gravel; if the strap is poorly positioned, the foot slides forward and the toes have to work with every step. There are only a few factors that make a difference, but they’re hard to gauge from a photo.

This guide covers these criteria in the following order: heel height, heel shape, the role of straps, the construction underfoot, and then occasions—from the office to dinner and a summer wedding. The goal is to choose one or two pairs of heeled sandals that you’ll actually wear—not just on the day you buy them.

Choosing the Heel Height: From Low Heels to Evening Heels

The height of the heel determines how long you can stand, long before the style or color does.

Low and medium heels, ranging from two to six centimeters

Heels between two and three centimeters are called low heels or kitten heels. They’re just enough to slightly lengthen the silhouette and take some pressure off the heel compared to a completely flat sole, without shifting too much weight to the front of the foot. This is the perfect heel height for long days, walking, and uneven surfaces.

With a heel height of between four and six centimeters, heeled sandals take on a more dressy look while still being comfortable enough to wear all day long, provided the heel is wide and the strap is well-placed. This is often the most versatile heel height: it pairs well with flowing pants at the office as well as a midi dress for dinner, and it’s still comfortable to wear late into the evening.

High heels, over seven centimeters

When the heel is taller than seven centimeters, the heeled sandal takes on a whole new character. Body weight shifts noticeably to the forefoot, the ankle works harder, and any flaws in construction become apparent more quickly. These are evening shoes, worn for just a few hours, often indoors and mostly while seated.

If you prefer this height, two features can significantly change the experience: an ankle strap that prevents the foot from sliding forward, and a heel that isn’t too narrow at the base. A slight platform under the forefoot also reduces the foot’s actual slope, given the same heel height. The best practice is still to try on the shoes at the end of the day, when your feet are at their largest.

Block heel or stiletto heel: stability versus a slender silhouette

The shape of the heel is just as important as its height when it comes to stability.

The block heel: a wider base

A block heel—whether square or slightly flared—provides a wider base on the ground. The foot stays more stable, the ankle twists less, and the heel sinks only slightly into grass or gravel. This shape makes it possible to wear a sandal with a five- or six-centimeter heel all day long.

It also has a more striking visual presence. Paired with a light-colored dress, a slim, slightly curved block heel maintains a sense of delicacy; paired with wide-leg pants, a more pronounced block heel balances the volume of the fabric. The leather-covered block heel, made of the same material as the straps, creates the cleanest silhouette.

The slim heel, a more slender silhouette

A thin, stiletto, or spindle-shaped heel elongates the leg and gives the sandal a more dressy look. On the other hand, the contact surface is reduced to just a few square millimeters: walking requires more care, as the heel sinks into soft ground and gets stuck in crevices.

They’re often reserved for indoor parties, dinners, and occasions where you don’t do much walking. In between, the medium-height tapered heel or the spool heel offer a compromise: a slimmer silhouette than a block heel, with a base slightly wider than a stiletto.

The strap: the part that holds the foot in a heeled sandal

An open-toe sandal does not have a closed heel counter to hold the heel in place; the straps do that job instead.

Ankle strap, back strap, instep strap

The ankle strap is the primary support feature. It prevents the foot from sliding forward with each step, which keeps the toes from tensing up to hold the sandal in place. An adjustable buckle allows for precise adjustment down to the millimeter—a feature that’s especially useful since the foot swells slightly in the heat.

The back strap, which goes behind the heel without wrapping around the ankle, provides less support but allows for more freedom of movement in the leg. The instep strap, positioned on top of the foot, distributes pressure and holds the foot in place without digging into the ankle. Sandals that combine a wide front strap with an ankle strap offer the most stability at the same height.

Width and Lining of the Straps

Thin straps give a more dressy look and leave the foot exposed; wider straps provide better support and distribute pressure more evenly. On a high heel, a strap that’s too thin concentrates pressure on a small area of skin and eventually leaves a mark.

It’s worth taking a close look at the inside of the straps. A leather-lined strap—with no seams that dig into the skin and neatly trimmed edges—is barely noticeable. A strap made of synthetic material or with raw, unfinished edges will start to chafe within the first few hours, especially when it’s hot.

• Ankle strap: maximum support, adjustable, recommended for feet 5 centimeters or larger
• Rear strap: medium support, more leg room
• Instep strap: holds the foot in place without digging into the ankle
• Mules without a back strap: best suited for low heels and short walks

Underfoot: Sole, Material, and Construction

The stability of a heeled sandal also depends on the inside and the sole.

The insole and the heel position

A leather insole absorbs some of the moisture and provides a slight grip for the foot, whereas a synthetic insole becomes slippery when it gets hot. The foot slides less toward the front, which relieves pressure on the toes and the straps. A light padding under the forefoot helps with heels over six centimeters high.

The position of the heel is also important. When positioned correctly, it sits directly under the heel bone and does not sit set back: the weight is distributed straight down into the heel instead of causing the foot to tilt. A simple test is to stand still while wearing the sandals: if you feel the heel wobble backward or inward, the balance of the pair is off.

The outsole and the material of the straps

A smooth leather outsole is elegant but tends to slip on smooth floors, such as tile or waxed hardwood. A thin rubber pad, placed under the forefoot, improves traction without adding bulk to the shoe’s silhouette. The heel tip—the small piece that touches the ground—wears out and can be replaced by a cobbler.

As for the straps, smooth leather and suede calfskin mold to the foot with repeated wear. Patent leather and synthetic materials remain stiff and may chafe. If you’re looking for a heeled sandal that will last for several summers, leather is the material that can be repaired, maintained, and will develop a beautiful patina over time.

Heeled sandals for any occasion: the office, dinner, a wedding

One pair alone won't cover every need, but two well-chosen pairs will take care of most of your summer needs.

At the office and for dinner

At the office, it’s best to keep heeled sandals simple: a block heel measuring four to six centimeters, clean straps made of smooth leather, in black, nude, or cognac. They pair well with wide-leg pants that partially cover the foot, a midi skirt, or a shirtdress. Days spent on your feet call for an ankle strap.

For dinner, sandals can be more elegant and refined: heels measuring six to eight centimeters, thinner straps, soft metallic leather, or suede calfskin. You won’t be walking much, so style takes precedence over comfort. A tapered heel or a slim, curved block heel provides stability while adding a touch of elegance.

For a summer ceremony

For a wedding or ceremony, the main consideration is the ground. A reception in a garden—on grass or gravel—makes it very difficult to wear stiletto heels, whereas a block heel of five to seven centimeters remains stable all day long. A secure ankle strap is essential if the evening goes late and there’s dancing.

The specific rules regarding color, attire, and heel height for the ceremony are detailed in our wedding shoe guide. Suffice it to say here that a leather block-heel sandal—chosen in a color that matches your outfit and broken in before the big day—can be worn from the reception through the end of dinner.
