Shin Splints Gait Analysis

Shin splints, or medial tibial stress syndrome, is a diffuse ache along the inside of the shin that builds over a few weeks of training, fades with rest, and comes back around week three of the next build. It's one of the most commonly recorded running injuries (Kakouris et al., 2021).

Bone adapts to load, but only as fast as it can repair. The variable that matters most is not just how much you run but how sharply force arrives on each step. Researchers call it the vertical loading rate, and high loading rates are associated with tibial stress injuries (LER review).

Loading rate is trainable. In the largest gait-retraining trial to date, runners coached to lower it had a 16% injury rate over the following year against 38% in the control group (Chan et al., 2018). This page covers what GaitLab Coach looks for when you flag shin pain.

Why shin pain builds

A foot landing well ahead of the hips acts like a brake. The ground pushes back against your direction of travel, and the shock travels up a relatively straight leg into the tibia instead of being absorbed by the ankle and knee. Shorter strides consistently mean lower impact forces and lower tibial loading (stride length and impact review).

Heel striking on its own isn't the villain. The problem is the combination: heel first, far in front, on a nearly straight knee. That bypasses the ankle's spring and produces the highest loading rates. The fix isn't forcing a forefoot strike, which just moves the load to the calf; it's landing closer to your hips with a slightly bent knee.

Cadence ties it together. At a low step rate you take fewer, longer steps, each spending more time on the ground and hitting harder. Raise it a modest amount and stride length shortens on its own.

  • Pain that appears after a jump in volume or speed and eases with rest
  • Shin soreness alongside heavy, loud, or slapping footfalls
  • A pattern that survives new shoes, compression sleeves, and rest blocks

What the video shows

Landing position

Pause at first contact and drop a line from your hip. A foot well ahead of it is the pattern that loads the shin.

Knee at contact

Straight transmits; slightly bent absorbs. A straight knee almost always accompanies a reaching foot.

Cadence

Measured on-device from the video. A 5–10% increase reduces vertical loading rate and joint loads without hurting economy (Sports Health, 2025).

Contact time

A foot that lingers on the ground usually means a longer, heavier stride.

What GaitLab Coach does with it

Flag shin splints before recording and the analysis weights its findings toward impact: landing position, knee angle at contact, cadence. Each finding in the full report is tied to the frame where it shows up, so you can check the landing yourself.

The 4-week plan for a shin case leads with a cadence cue and landing drills (A-skips, wall lean), adds eccentric calf work so the calf takes more of the load, and keeps mileage flat while the pattern changes. One or two prioritized changes beat a checklist (Bramah et al., JOSPT 2022).

  • Findings ranked by how much they change loading rate, not by how visible they are
  • A plan that changes one thing at a time so you can tell what worked
  • A re-test after four weeks that compares landing position and cadence against your baseline clip

When form isn't the culprit

Shin pain is often a training-load story: too much, too fast, too soon, a sudden switch to much firmer or softer shoes, poor sleep, or under-fuelling. Form work doesn't fix a reckless build. And some shin pain isn't shin splints. Pain that is sharp and focused on one spot on the bone, hurts when you hop on one leg, or aches at rest and at night is a red flag for a bone stress injury and needs a clinician before any drill work. GaitLab Coach flags movement patterns; it can't examine bone.

Shin Splints FAQ

Can running form cause shin splints?

Form decides how sharply force arrives at the tibia on each step. Overstriding and heel-first landings on a straight knee produce high loading rates, which are associated with tibial stress injuries. Retraining that lowered impact loading cut injury occurrence in a year-long RCT.

Do I need to change my foot strike?

Usually not directly. Land closer to your hips with a slightly bent knee and your strike pattern tends to soften on its own. Forcing a forefoot strike moves the load to the calf and Achilles.

Should I see someone before doing form work?

If the pain is sharp, localized to one spot, present at rest, or worse when hopping, yes, to rule out a bone stress injury first.
