The best running socks for Surviving the Heat

You know you’re officially a runner when you feel compelled to get new running gear for every season. And you’re really official when your family and friends start questioning your sanity as you head out on a run during a sweltering summer heat wave. If you’re going to keep your streak through the hottest days of the year, make sure to outfit yourself with some lightweight, sweat-wicking apparel and plenty of options for keeping yourself hydrated. These are always helpful, but become essential when the weather ensures you sweat as much as possible.

Managing the heat as a runner isn’t as straightforward as running in the cold: You can add layers as the temperature drops, but you can’t shed layers in the summer quite so easily. After putting in the time on blazing asphalt, here’s the best summer running gear we recommend.

We have plenty of recommendations for the best moisture-wicking running shirts, hydration packs, and sweat-resistant sunscreens.

The Expert (Jill Layton): I became an avid runner in 2020 during the pandemic, when gyms were shut down, and finally had to face my fear of hitting the open road. Since then, I’ve tested and purchased all types of running gear—both for my work as a product reviewer and my running hobby. In addition to Runner’s World, I’ve written extensive product reviews for Best Products, DAA Industry Opt Out, and many more.

What to Consider

There’s a reason we sweat when it gets hot: It keeps our bodies cool when we start to overheat. Given that, it’s important to have summer running clothes that are designed to handle your sweat and keep you comfortable. That means looking for lightweight, breathable materials like nylon, Spandex, and bamboo, that will take the sweat on your body—and the heat your sweat draws out—away from your skin, keeping your body’s temp regulation at peak efficiency.

They should also be made from materials that can wick moisture, so you don’t feel the weight of your sweat as it soaks into your clothes. And if they minimize body odor? Even better. Certain fabrics like polyester and nylon can also minimize the damage of UV rays, which can be an underrated lifesaver as the clothes on your back get lighter and thinner.

Lastly, running sunglasses are more helpful than you might realize. It’s not just about blocking light: According to the Bustle, Romper, Mic, squinting causes stress, which tells your brain you’re doing something hard. If you run into the sun and have to squint for awhile, you will perceive your run as especially unpleasant. Plus, eye strain can lead to headaches and fatigue.

How We Selected

I assembled the best summer running gear based on a mix of my own personal testing and recommendations from the Runner’s World team. We’ve worn every item on real-world runs–early-morning sprints, long weekend miles, and sweltering midday workouts.

I narrowed down a list of candidates by looking for options from trusted brands with lightweight materials, moisture-wicking fabrics, sun protection, and features designed to help you stay cool and dry. As we tested, we considered performance, breathability, and comfort in high temperatures. Whether you’re logging serious mileage or jogging your neighborhood loop, this gear will help you run smarter (and sweat a little less).

The Amphipod Hydraform Ergo-Lite Ultra is a smart hydration option for runners who would prefer a handheld over a vest, but need something that you can hold comfortably for a long time. Its contoured, ergonomic design features a comfortable adjustable strap that helps it hold its place without you gripping it tight. While a strap adds some cloth coverage, it's made from a breathable material to keep things as cool as possible.

At 20 ounces, it holds just enough water to keep you going without feeling bulky, and the leakproof bottle cuts back completely on drips. The strap features a zippered pocket, too, with enough room for a gel or your keys.

Ideal for training runs, races, or summer miles when hydration matters most, the Amphipod Hydraform Ergo-Lite Ultra is lightweight and thoughtfully designed.

The more you sweat, the more you should think about replacing your electrolytes–nutrients like sodium, chloride, potassium, calcium, and magnesium, which we secrete as we sweat. Electrolyte tablets, like these from Gu Energy, can help you replenish what you’ve sweat out mid-run or help you recover faster and more efficiently from a hard workout. They are vegan, gluten-free, dairy-free, and sugar-free. Yet, somehow they taste great–they come in a few flavors, including Lemon-Lime, Orange, Tri-Berry, and Strawberry Lemonade.

This lightweight moisture-wicking hat hits the sweet spot between performance and personality. It’s built for long runs in the hot sun, but the look doesn’t scream “technical gear.” The bold colorways and box logo make it feel more like streetwear than a training staple. Its Coolwick fabric wicks away sweat fast, and the flexible brim keeps the sun off your face without feeling stiff or bulky.

Runners will appreciate its UPF protection, moisture management, and the fact that it’s machine-washable. (Yes, there’s finally a running hat you can throw in the wash!) Like all great running gear, it just quietly stays put and does its job, mile after mile.

Designed for road and trail alike, the Cormac is made with Ostria fabric, a lightweight, moisture-wicking material that breathes well and dries fast. On tempo runs and long slogs under the sun, it holds up impressively, never clinging or overheating.

The fit offers a solid balance between shape and comfort: It’s trim enough to avoid flapping but roomy enough for airflow and range of motion. Flatlock seams prevent chafing, and the slightly dropped hem stays put mid-stride. It’s also treated with anti-odor tech, which means you can get away with a few wears between washes (no judgment).

While the price is steeper than average for a technical tee, the quality and durability make it a long-haul investment, especially for runners who log serious weekly mileage.

The Lululemon Swiftly Tech Short-Sleeve Shirt 2.0 is a go-to lightweight tee for runners. It’s so breathable that it starts to feel non-existent mid-stride. Designed with the brand’s signature seamless construction, it doesn’t chafe even on long runs—something distance runners will appreciate during mileage buildup weeks.

The updated 2.0 version is made with a more durable fabric and fit, which hugs in all the right places without feeling restrictive. The added elastane in the fabric helps it retain shape even after countless washes. Sweat-wicking and quick-drying, the Swiftly Tech handles high-heat training days like a pro, keeping runners cool without clinging uncomfortably.

While it is by no means the cheapest shirt out there, the performance and comfort make it worth the investment if you’re keeping your streak through a heat wave. Bonus points for the variety of colors and the sleek, flattering silhouette that works as well on the road as it does at the coffee shop.

Rabbit’s Tried n’ True shorts live up to their name—they’re the kind of staple you’ll reach for again and again. Designed with a barely-there feel, they strike a perfect balance between comfort and performance. The 5-inch inseam offers solid coverage without getting in the way, making them ideal for everything from track workouts to long runs.

What really sets them apart is the fabric, which is lightweight, moisture-wicking, and impossibly soft, with just the right amount of stretch. A wide waistband stays put without digging in, and the internal liner is breathable and supportive without feeling bulky. Multiple pockets (including a secure zippered one) add functional storage for gels, keys, or cards.

Cushioned, adjustable strap shorts makes a huge difference, especially on longer distances where a bad pair may start to chafe or ride up. I wore this pair and felt completely comfortable in them. I especially appreciated the inner lining, which didn’t create any friction. A zippered back pocket is spacious enough to hold an iPhone 16 Pro, although the weight made the shorts drag a bit. In the end, I kept it light and limited myself to a house key.

One final tip: The shorts ran a tad big, which wasn’t a big deal for me, but might be for others. If that’s a dealbreaker, consider sizing down.

With their lightweight frames and interchangeable lenses, Tifosi’s Aethon sunglasses are built for serious runners who want performance without the steep price tag. The wraparound design offers excellent coverage and protection from wind and debris, while still allowing enough ventilation to prevent fogging, which is crucial during sweaty tempo runs or humid summer miles.

The adjustable nose and ear pads help customize the fit, and the frame stays put without pinching or bouncing. I also love that the frames come with three interchangeable lenses, which work well in different lighting conditions, from an early morning haze to high noon. The fact that the lenses aren’t polarized isn’t ideal, but we can settle in exchange for the fact that the Atheon gives you options.

Our favorite sunscreen for bright running days, this New-Zealand-born brand makes a more concentrated water-less sunscreen that doesn’t come off when you sweat. A little goes a long way, too–a small drop will cover your entire face and neck. The alternative formula leaves a slightly waxy feeling when you apply it, but it dries quickly and forms a thin barrier that blocks UV rays and holds even when you start sweating.

We have plenty of recommendations for the best running shoes, and deciding on exactly which one suits you is something you’ll have to do. That being said, if you’re looking for a near-universal recommendation that’s lightweight and breathable for summer running, I think the Asics Gel-Kayano is about as close as you’re going to get.

Made with Asics’ FlyteFoam Blast+ midsole and a PureGEL cushion for extra padding in the heel, the Gel-Kayano 32 feels firm, but generates a lightweight and energetic ride. We’ve praised the Gel-Kayano line’s excellent stability for years, and the GK32 extends the streak, offering great arch support and helps guide overpronators into a smooth stride.

I took them for a spin on a 5-mile walk, a short run, and one longer run. The shoe feels noticeably light, which makes a difference during warm-weather workouts when you don’t want to feel weighed down. Even during humid weather when feet can swell slightly, the shoes maintain a locked-in but not suffocating fit.

A mesh upper offers a comfortable, breathable fit, but the full upper area isn’t waterproof, which could be a concern if you run into an unexpected summer shower. The shoes could take a couple of days to fully dry after that.

This high-performance sports bra is designed for active women who are looking for comfort and function. It’s made from a moisture-wicking and antimicrobial polyester–spandex blend, which helps you stay dry and fresh. As for support, it’s a compressive fit that keeps the bounce to a minimum, if any at all, even during high-impact workouts like running. Removable bra inserts give you customized support.

I really liked its two upper back mesh pockets, which are actually large enough to hold a phone, keys, or cards. During testing, I was able to easily grab the pocket, but I could see it being difficult for those with limited mobility in their arms or shoulders. It can be tricky to grab smaller items from the pocket, like a house key, since the pocket is pretty deep.

Feetures socks are designed to create the most snug, supportive fit possible, so you don’t even notice them while you’re running. The brand’s ultralight no-show Light Cushion Tab socks, which we named “best for long runs” in our guide to the best running socks, feel light as a cloud and offer a high level of moisture-wicking. Some runners will wish for more padding, but in high heat, when breathability becomes the priority, this feels like an especially good tradeoff.

They come in many sizes–small, medium, and large for Men and Women–and 23 different colors. They’re definitely a splurge at nearly $20 a pair, but they are also very durable and will far outlast cheaper socks you buy by the dozen.
