These Are the Running Patterns That Predispose Runners to Certain Injuries as Mileage Increases, Podiatrist Says
More often than not, when your feet start screaming at mile six, the shoes take the rap. You convince yourself the cushioning is dead, the foam is "incompatible" with the trail, or you simply logged one too many sessions in them. But your footwear isn't always the villain in this story. It’s entirely possible that your own stride is the one staging a silent coup, sabotaging your feet in ways that are invisible to the untrained eye.
"As mileage increases, small biomechanical inefficiencies become magnified and can lead to overuse injuries," says board-certified podiatrist and foot and ankle surgeon Dr. Bobby Pourziaee.
If you’re a beginner knocking out a mile or two a week, these little hitches in your gait usually fly under the radar. But as you climb the leaderboard, those tiny inconsistencies are repeated thousands of times per run, which significantly raises the risk of a breakdown mid-stride.

So, what does that actually look like? Well, according to Pourziaee, it usually manifests in a few specific ways, the most common being excessive overpronation, a classic struggle for the flat-footed crowd. This happens when a runner’s foot rolls inward more than 15 degrees during the landing phase, causing the arch to flatten like a pancake.
"Runners who excessively overpronate may place increased stress on the posterior tibial tendon, which can lead to tendonitis or progressive flatfoot symptoms," Pourziaee adds.
On the flip side, runners with rigid, high arches are also in the line of fire. They’re more prone to stress fractures because their feet absorb shock with all the grace of a brick. Other biomechanical offenders include excessive "vertical oscillation" (basically bouncing too much), which cranks up the repetitive impact forces.
Then there’s hip weakness. When your glutes check out, it causes abnormal loading patterns that travel down the chain, wreaking havoc on the knee and ankle. Even limited ankle dorsiflexion, something Pourziaee says can be fixed with proper stretching, can ruin your day by shifting the load toward the forefoot and putting your metatarsal bones through the wringer.

How to Build a Better Base
"Before increasing mileage, runners should prioritize improving both mobility and strength
in the foot and ankle complex," Pourziaee says. "One of the most important areas to address is ankle dorsiflexion mobility, which can be improved through exercises such as knee-to-wall ankle stretches. Limited dorsiflexion is a common contributor to altered running mechanics and increased forefoot stress."
Ultimately, limited dorsiflexion is a silent killer for your form, contributing to altered mechanics and increased forefoot stress. So, before you drop $200 on new carbon-plated super-shoes, spend five minutes on the wall stretching your calves. Your bank account (and your metatarsals) will thank you.
