Introduction
Carbon-plated racing shoes have been everywhere in running culture, boasting up to 2–4 % improvements in running economy compared to traditional trainers. That sounds like a no-brainer—who wouldn’t want to run faster for less energy? But here’s the catch: for everyday runners and many recreational athletes, these performance gains can come with trade-offs. As a chiropractor who works with many runners here in Toronto, I regularly see pain and injuries linked to these shoes—especially in runners with biomechanical issues like overpronation or wider feet.
Do Carbon Plate Shoes Really Improve Running Economy?
Studies have shown that advanced shoe technologies combining carbon plates with high-energy-return foams can lower metabolic cost and oxygen consumption by roughly 2–3 % during submaximal running, often measured by reduced oxygen use at a given pace. This is where the oft-cited 2–4 % improvement in running economy comes from.
However, the plate itself may not be the sole reason for improvements. Some research suggests that the foam and overall shoe properties contribute more to energy savings than the carbon plate alone. In one study where carbon plates were added to shoes solely to increase bending stiffness, there wasn’t a clear improvement in running economy — suggesting that the mechanical contribution of the plate by itself might be smaller than many runners assume.
The Hidden Trade-Off: Joint Stress and Compensation
While carbon-plated shoes can help with efficiency, several biomechanical studies and systematic reviews indicate alterations in how forces travel through the lower limb:
What all this means: a shoe that reduces the energy cost of running might simultaneously increase demands on the joints and soft tissues—especially when you’re tired late in the run.
Why I See More Pain and Injuries in These Shoes
As a chiropractor who helps runners with pain, posture, and running mechanics, patterns have emerged:
1. Overpronation and Lack of Support
Runners who overpronate (roll inward) often rely on mid- to high-support shoes or orthotics to keep their gait stable. Carbon-plated shoes are typically low-support and rigid, so they don’t work well with custom insoles or orthotics, which can’t be installed without altering the shoe’s performance. This can exaggerate pronation and contribute to stress on the ankles, knees, or hips.
2. Narrow Shape and Stability Issues
Many carbon-plated models have narrow toe boxes and limited structural support. Runners with wider feet often find them unstable—and that instability can manifest as ankle sprains, forefoot pain, or knee discomfort because the foot can’t get a secure platform under it.
3. Benefits Depend on Running Speed
Fast runners at or near elite paces tend to derive more of the measurable advantage from carbon plates due to how they interact with stiffness and ground reaction forces. Recreational runners at slower paces often see little to no real improvement in economy, yet still feel the structural changes in the shoe. In my experience, that’s where mismatches between expected performance gains and actual comfort/injury risk happen most.
The Case for Isometric and Strength Training Alternatives
Interestingly, research also shows that strength training interventions—like certain isometric exercises—can produce improvements in running economy without structural compensation from footwear. Older studies reported ~4–7 % improvements in running economy after isometric plantar flexor training, suggesting tendon and muscle adaptations that help you run more efficiently from the inside out.
Isometric work can improve tendon stiffness and force transmission, which helps the body store and return elastic energy more effectively, similar in magnitude to what some people hope to get from super-expensive shoes—but with fewer compensations and lower injury risk when done properly under guidance.
So, Are Carbon-Plated Shoes “Bad”?
Not at all—but they’re not one-size-fits-all. They can be a useful part of a race day tool kit for experienced, efficient runners who already have robust biomechanics, strong feet/ankle muscles, and can tolerate the stiffness. For many everyday runners, they may:
What I Tell My Patients
As a corrective chiropractor in Toronto working with many runners—drawing on more than a decade of experience that includes my time in the running shoe retail world (Running Room employee)—I always start with the individual, not the shoe. A shoe should support your movement pattern, not force your body to adapt to it.
Often, the real gains in performance come from strength, mobility, and improving running mechanics rather than chasing small economy gains through footwear alone. Tools like carbon-plated shoes can have their place, but they’re not a universal solution and shouldn’t be expected to fix mechanical inefficiencies.
