As a runner, what you do off the track, road, or trail often has just as big an impact on your race performance as what you do on it. Research shows that regular cross-training—plyo circuits, power lifting sessions, bootcamp-style workout classes, or even cycling—can help make you fitter, stronger, and faster. But first, to really boost those benefits and reduce your risk of injury, you need to swap your regular running shoes for a training-specific style, like the ones below. Keep reading to learn why and how these workout shoes give you the stability, bounce, and support you need—and why your high-mileage pairs probably don’t.

The Expert: This guide builds on the work of fitness editor Lindsey Emery, a runner and reviewer of gear related to health and wellness. To update the product selections, I added my knowledge and experience as a runner, multisport athlete, and dabbler in the CrossFit world. I’ve been a shoe reviewer at Runner’s World for more than 10 years, both on staff and as a freelancer. In that time, I’ve tested dozens upon dozens of running and cross-training shoes, so I’m well-versed in seeking out features that make a great trainer.

What to Consider When Choosing Cross-Training Shoes

A good cross-training shoe provides the versatility for tackling both strength training and cardio workouts, while also being specialized enough to support specific activities in your training plan. Unfortunately, there’s no one shoe that works equally well for everyone and every workout—your footwear needs will likely vary based on interest, fitness level, and foot type. But we’ve found that some shoe features function well across the board, whether your workout takes you to the treadmill or the CrossFit box. Here’s what to look for.

Lighter, more flexible cushion at the midsole

Cross-training workouts often include sprints and short bursts of running, which makes a certain amount of midsole cushion essential for comfort and impact absorption. But unlike in running, those workouts are also more likely to incorporate lateral movements, as in skaters, side-to-side lunges, grapevines, and side shuffles. For this reason, you’ll want wider, more stable shoes with less cushion underneath for a more grounded feel, plus more flexibility at the midsole for multidirectional movement. You’ll also want a lower heel-toe drop than you might in a running shoe, and more even cushioning throughout.

A flatter sole or lifted heel

Weight lifters in particular often do well in flat-soled shoes that have a firm midsole and wider base for better grip on the floor. This provides a better sense of stability than with cushy running shoes, as your feet can spread out and feel more connected to the ground beneath. Other lifters prefer more dedicated weight-lifting shoes with a raised heel of up to an inch. This stiff, firm wedge helps the body better maintain alignment during lifts and squats. Good cross-training shoes for weight-lifting incorporate these characteristics but also integrate cardio-friendly features like softer forefoot cushioning and more breathable uppers.

A grippy, durable outsole

Cross-training movements tend to put more wear and tear on a shoe, due to their dynamic range of movements. For this reason, you’ll want to look for shoes made of long-lasting materials with targeted reinforcement in the outsole—including high-traction tread that won’t slide on the gym floor or blacktop.

An upper that provides solid lockdown

Most running shoe uppers are designed to be lightweight and breathable above all, but a good cross-training upper needs to be beefier, more durable, and secure-fitting without losing that same sense of comfort. To support more explosive, multidirectional movement, you’ll often find added TPU overlays and Velcro straps on cross-training uppers that lock down the foot and hold it securely in place.

How We Selected These Cross-Training Shoes

To make these recommendations, we looked for cross-training shoes with design elements that help support multi-directional movements, explosive workouts, cardio/strength circuits, and heavy lifting sessions. These features include flexible uppers, cushioned (yet firm where you need it) midsoles, minimal heel-to-toe drops, reinforced heels, extra grip, and protective overlays. Some of these shoes have been tested by the Runner’s World test editors and wear test team; others were selected on the basis of experience with earlier iterations of the shoe or extensive research of online reviews. We started in 2021 with a list of 12 and updated in 2022 to include the best new releases.

This new max-cushioned trainer is designed for running and cardio-heavy cross-training—and we found it to be a comfortable and effective option for both. The Kawana is slightly heavier than some of our favorites from Hoka, like the Clifton and Mach, but it boasts a similar abundance of cushion, high rebound, and smooth ride from its supportive, somewhat firm midsole. The breathable mesh upper provides a generous fit with solid foot lockdown for movement in all directions. Although the shoe feels great for HIIT workouts and running, it might not be the best choice for weight lifting, due to its soft midsole and high stack. The rubber outsole’s traction also drew mixed reviews from our testers—we suspect it’s better suited to the gym and not wet pavement.

The Project Rock 4 is a dedicated cross-training shoe designed to be as versatile and multi-talented as its actor and wrestler namesake, Dwayne Johnson. And with each new iteration of the eponymous shoe, Under Armour has incorporated more of its best technologies aimed at making you feel fast—and furiously strong—in the box. The 4 boasts a HOVR foam midsole that feels springy and responsive as you burst into motion during HIIT workouts. The low heel counter provides good foot lockdown and a stable base, while the raised heel helps you maintain postural alignment while lifting. The shoe’s “Tribase” outsole design is equally multipurpose: Triangle-shaped grooves in the synthetic rubber provide solid grip indoors and out, while allowing the shoe to flex multi-directionally for forward and lateral explosive movements. The biggest difference between this shoe and the previous model is up top—the 4 has a TPU strap at the midfoot for enhanced foot lockdown, as well as a more breathable engineered mesh upper with an anatomical sock liner and less of a bootie-like design.

The F-Lite 235 V3 packs quite a bit of performance into a relatively streamlined cross-training shoe—with a plush feel (especially for a shoe with a minimal 4mm heel-to-toe drop) and a midsole that provides good cushioning under the heel and returns a solid amount of energy in the forefoot. The upper also takes advantage of two different types of mesh: a finer, firmer mesh adds rigidity along the outside of the shoe and, along the inside, a more loosely woven mesh adds breathability and flexibility so your foot can move around freely and comfortably. The gum rubber outsole also allows for natural foot movement with its segmented, metatarsal-like channels that run heel to toe. The abundance of durable synthetic overlays will speak directly to CrossFitters looking for extra protection for intense activities, like rope climbs and box jumps, but these lightweight, free-moving trainers should interest anyone looking for something that feels a little more natural (er, barely there) underfoot.

You Should Definitely Cross Train and, Yes, You Need the Right Shoes to Do It, According to Our Expert, Caitlin Giddings

RW: How do cross-training shoes differ from running shoes?

CG: For a more thorough answer to this, check out the “what to consider” section above. Essentially cross-training shoes tend to have more durable uppers; thinner, firmer, and more flexible midsoles; minimal heel-toe drops, except in the case of weightlifting shoes with reinforced heels; extra grip in the outsole; and protective overlays to better hold your foot into place. Many of these cross-training styles are built on lasts that are similar to your favorite running shoes; however, they also provide added stability and flexibility for all your workouts.

RW: How far can you run in cross-training shoes?

CG: Most cross-training shoes are designed to be worn for runs up to a mile or even two. However, many are only designed for quick sprints and cardio—so the distance you can comfortably run in a cross-training shoe depends on both the amount of cushion underfoot and your personal need for support while running.

RW: Why should runners cross-train?

CG: A recent study published in the Journal of Sport and Health Science revealed that runners who completed plyometric workouts twice a week improved their performance—and their power—in just six weeks (or 12 sessions total). And another study, published in the European Journal of Applied Physiology, showed that even well-trained ultramarathon runners had room for improvement: After 12 weeks of incorporating explosive plyo workouts into their routines, they saw a boost in their running economy, or their ability to run faster and longer, while using less energy. For most runners, cross-training adds variability to an all too often monotonous routine. When you log miles without doing anything else, your muscles adapt to the work and, because they’re never pushed beyond the limit they’ve already reached, your strength gains begin to taper. Your progress plateaus. Your risk for overuse injuries increases. But building regular cross-training into your running schedule (especially when it’s done strategically, under the guidance of a coach or trainer) can improve strength, power, speed, and even aid in your recovery.
