Best Trail Running Shoes (2026)
Trail running shoes are low-cut, flexible shoes built for running and hiking over rough terrain, and more backpackers are choosing them over traditional boots every season. They trade the stiff support and ankle-high cuff of a boot for a lighter, more athletic shoe that flexes with your foot and dries out fast when it gets wet, which can make miles on trail feel noticeably easier.

In plain English
Trail running shoes look like ordinary running shoes, but with grippier rubber underneath, tougher toes and deeper tread for dirt and rock. Many hikers wear them instead of boots because they're light, comfortable from day one, and dry quickly after they get wet.
Think of the choice like a bike versus a truck. The trail runner is light and quick, but it offers less protection and wears out sooner. A boot is heavier and sturdier. KEEN, which makes both, describes lighter shoes as built for low weight and breathability and boots for durability and weather resistance.1
Fit is still the most important part. Your feet swell during a long day, so try shoes on in the afternoon, wear the socks you'll hike in, and leave a little space in front of your toes so they don't hit the end on the way downhill.3
Who it's for
Trail runners suit day hikers, weekend backpackers and thru-hikers who want to move fast and light and are comfortable strengthening their ankles over time. They're a great fit for warm, dry climates and well-maintained trails. Hikers carrying very heavy packs, tackling technical scrambles, or with a history of ankle injuries may still prefer the added support and durability of a boot.
How to choose a trail runner
Trail runners are lighter and require no break-in, so most people find them comfortable straight out of the box, and mesh uppers drain and dry quickly after a stream crossing or rainstorm. The trade-offs are less ankle support, thinner materials that wear out faster, and more foot fatigue under very heavy packs. Weigh your typical load and terrain before choosing.
Feet swell over a long day and swell more in the heat, so leave room at the toe without letting the heel slip; about half an inch ahead of your longest toe is the usual fit target. Downhill sections push toes forward, so look for enough length and width in the toe box that your toes don't jam into the front. Try shoes on in the afternoon and with the socks you'll actually wear.
The outsole's rubber compound and lug pattern determine how well a shoe grips loose dirt, mud, roots and rock. Deeper, widely spaced lugs bite into soft or muddy trail but feel less stable and wear faster on pavement and slickrock. Shallower, closely spaced lugs suit hard-packed or rocky terrain. Match lug depth to the surfaces you hike most often.
Stack height is how much foam sits between your foot and the ground, and drop is the height difference between heel and forefoot. More cushioning and higher stack absorb impact on long days and hard surfaces but can feel less stable on uneven ground. Lower-stack, lower-drop shoes give more ground feel and stability at the cost of some comfort over distance.
Waterproof membranes keep your feet dry in light rain and short splashes, but once water gets in over the collar or through a seam, it stays trapped and the shoe takes far longer to dry. Many hikers prefer a plain breathable mesh shoe that lets water drain straight out and dries out as you walk, saving the waterproof option for cold, wet, low-splash conditions.

Why a light shoe changes the whole day
The strongest argument for trail runners comes from load-carriage science. A review of soldier load carriage by Knapik and colleagues found that each kilogram added to the feet raises energy expenditure by about 7 to 10%, compared with roughly 4% per kilogram on the thigh.2 Feet are lifted, swung and set down thousands of times a day, so small weight savings there add up. The same review notes that energy cost also rises with load weight, body mass, walking speed and grade, so footwear is one factor among several.2
The flip side is protection under load. A 2026 study of long-distance hikers found that packs heavier than about 10% of body weight produced a clear, load-dependent rise in pressure on the soles of the feet.6 A thinner, more flexible shoe spreads less of that pressure, which is why the page steers very heavy loads toward more supportive footwear and why cushioning matters more as pack weight climbs.
Boots or runners: what the sources actually say
Much of the trail-runner-versus-boot debate rests on hiking-community experience rather than published research. In this site's research library, the only source directly comparing the two is KEEN, a footwear brand. KEEN says a boot's extra stability and support can be welcome with a fully loaded pack, and that lighter shoes are designed to be lightweight and breathable.1 Treat that as the maker's framing. The page's point that ankles strengthen over time in low shoes is common advice, not a measured finding.
On sizing, a neutral source is available. OrthoInfo, from the American Academy of Orthopaedic Surgeons, says feet can swell up to 8% during the day, recommends leaving about half an inch between the longest toe and the tip of the shoe, and says to size for the larger foot.3 Whether that works out to a half size up depends on your foot and the shoe's last, so measure rather than assume. On injuries, a 2023 review found blisters and ankle sprains were the most common hiking injuries, but it did not compare footwear types.7
Extending a runner's range: gaiters, cold and wet
Low-cut shoes have an open collar, so sand, grit and small stones get in and grind against your socks. Short gaiters seal around the footwear to keep dirt, dust, rocks and snow out.4 That small addition removes one of the main blister triggers on dry, loose trails.
The quick-draining mesh that works so well in summer becomes a liability in cold weather. NIOSH says wet feet lose heat 25 times faster than dry feet and that trench foot can develop at temperatures as high as 60°F if feet stay wet.5 The Park Service recommends wool or polypropylene socks because they keep feet warm even when wet.8 For cold, wet trips in mesh shoes, pair warm socks with a dry pair for camp, or consider a waterproof model for low-splash conditions as the page suggests.
Common questions
Are trail running shoes durable enough for backpacking?
They're less durable than boots, typically wearing out faster underfoot and through the mesh upper, especially with heavy pack weight or abrasive terrain. Most hikers accept this trade-off for the comfort and weight savings, treating trail runners as a shoe to replace more often rather than a single pair meant to last for years.
Do I need to break in trail running shoes?
Generally no. Trail runners use flexible, low-profile materials that feel close to a regular athletic shoe from the first wear, unlike a stiff leather boot. Even so, it's worth taking a new pair on a few shorter walks before a long trip to confirm the fit and rule out any rubbing or hot spots.
Will my ankles be okay without high-top support?
Most hikers adapt well, since trail runners let your ankles move and build stabilizing strength over time rather than relying on a boot's cuff. People with a recent ankle injury, chronically weak ankles, or a habit of rolling them on uneven ground may still want the extra support a boot or a supportive gaiter setup provides.
