Sneaker Upper Materials: Leather, Mesh, and Synthetics

What the upper does

The upper is everything that wraps over your foot. It holds the midsole to your foot, affects how the shoe breathes, how much it weighs, how it flexes, and how much support it gives. The material you choose changes the personality of the sneaker more than any other single component.

You do not need one perfect material for all occasions. Instead, match the upper to what the shoe will do: daily walking, running, gym sessions, or casual wear. A leather upper on a running shoe can weigh you down, while a mesh upper on a dress shoe might look out of place. Consider how often you plan to wear the shoe and what kind of weather you will be in.

Leather uppers

Leather is the traditional upper material. It is smooth, durable, and forms to your foot over time. A leather sneaker can feel supportive and structured, which is why it is common on court shoes, dress sneakers, and everyday wear. It also tends to be heavier and less breathable than mesh, so it can feel hot in summer.

Leather stretches with use, so a pair that fits snugly at first can become more comfortable after a few wears. It also resists scuffs better than many fabrics. If you want a sneaker that lasts and looks good as it ages, leather is a strong choice. See our best leather sneakers for a range of styles.

Mesh uppers

Mesh is a woven fabric, often made of nylon or polyester. Its open weave lets air move in and out, which helps keep your feet cool. Mesh is also lightweight and flexible, making it a favorite for running and training shoes. The tradeoff is that mesh offers less structure and can wear through faster, especially at the toe or where your foot bends.

Mesh sneakers dry quickly after rain or sweat, and many are machine washable. If you run regularly or live in a warm climate, a mesh upper can make a big difference. Our best running sneakers list includes many mesh models.

Synthetic uppers

Synthetic uppers include a wide range of materials, from engineered knits to coated plastics. These are created to mimic specific qualities: some copy the look and feel of leather, others copy the stretch and breathability of mesh. Synthetics are often lighter than leather, more durable than cheap mesh, and can be made water-resistant with a coating.

Because the term 'synthetic' is broad, always check the sneaker's description for what kind of synthetic is used. Some have excellent ventilation, others are almost completely sealed. If you want a versatile shoe that balances breathability and protection, a synthetic upper is a safe bet. For everyday options, look at our best everyday sneakers.

Comparison at a glance

The table below summarizes the typical characteristics of each upper type. Keep in mind that exact performance depends on the specific construction and materials used by the manufacturer. For example, a woven synthetic can be more breathable than a solid one, and certain leathers are thinner and more flexible than others.

How to choose for your use

Start with what the sneaker is for. If you walk a lot and want a stable, long-lasting shoe, leather or a sturdy synthetic will give you support. If you run or do cardio, breathable mesh keeps your feet cooler and reduces weight. For a casual sneaker you wear to work or out, leather or a premium synthetic looks sharp.

Feet that sweat a lot will do better with mesh or an engineered knit. If you need extra width, leather can stretch more easily than mesh, so it can be more accommodating. Consider the climate too: mesh in summer, leather in winter. For specific advice on fitting, see our guide on how sneakers should fit.

Upper and foot support

The upper also plays a role in how much support your foot gets. Leather and stiff synthetics can hold your foot more securely, which helps during lateral movements such as in tennis or basketball. Mesh tends to be more flexible, so it allows a wider range of motion but offers less structure.

If you have flat feet or overpronate, look for sneakers with a firm upper and additional internal support. You can also read our article on neutral vs. stability shoes to understand how the upper and midsole work together. Trying a few models in the store is the best way to feel the difference.

Care and longevity

How you clean your sneaker depends on the upper. Leather needs a gentle cleaner and conditioner to keep it supple. Mesh can usually be brushed or rinsed with mild soap. Synthetics vary, so check any care tags. No upper lasts forever, but regular cleaning and allowing shoes to dry completely help them hold up.

Rotate between two pairs if you use one every day. That gives moisture a chance to evaporate and helps the upper retain its shape. For more on keeping sneakers fresh, read our sneaker durability tips or the cleaning guide.

What to pick for your use

Questions

Is leather or mesh better for sweaty feet?

Mesh is more breathable, so it is better for sweaty feet. Leather traps heat and moisture. If you sweat a lot, choose mesh or a synthetic knit that allows air circulation. You can also look for sneakers with moisture-wicking linings to help keep your feet dry.

Do synthetic uppers wear out quickly?

It depends on the quality. Some engineered knits are durable, while cheap coated synthetics can peel. Look for sneakers with reinforced overlays in high-wear areas. Generally, a well-made synthetic will last as long as leather for everyday wear, but you should inspect the stitching and coating before buying.

Can I run in leather sneakers?

You can, but they will be heavier and less breathable. For running, mesh is the standard because it keeps your feet cool and light. Leather sneakers are better for casual wear or low-impact activities like walking or light gym work. If you want a running shoe for daily miles, pick a mesh pair.

Do mesh sneakers stretch out?

Mesh does stretch some, but not as much as leather. A mesh upper that is snug at first will loosen slightly with wear. If you need more room, leather is more forgiving. For a mesh shoe, it's important to start with the right size because you cannot rely on much stretch.

How do I clean leather and mesh differently?

Leather should be wiped with a damp cloth and a dedicated leather cleaner, then conditioned to keep it soft. Mesh can be brushed with soapy water and rinsed, and some mesh sneakers are machine washable on a gentle cycle. Synthetic materials follow the care label on the shoe; many can be wiped clean.

Which upper material is best for wide feet?

Leather tends to stretch and conform to your foot, so it is often the best choice for wide feet. Mesh can be flexible but may not give as much. Look for sneakers marketed as wide-fit if you need extra room. Learn more in our guide on wide fit sneakers.
