Barefoot running with PTTD: Is it safe?

The barefoot running trend has passionate advocates and vocal critics. If you’re dealing with posterior tibial tendon dysfunction (PTTD), you might be wondering whether ditching the shoes could help or hurt your recovery. Let’s take an honest look at the science and practical considerations.

The barefoot running debate

Barefoot running enthusiasts argue that our feet were designed to run without cushioned heels, and that traditional running shoes have actually weakened our feet. They point to cultures where people run barefoot without the injury rates we see in modern runners.

On the other side, podiatrists and orthopedic specialists note that the human foot has evolved to handle the surfaces we historically ran on (soft earth, grass, and sand), rather than hard concrete and asphalt.

The truth is somewhere in the middle, and when you have PTTD, caution is particularly important.

Why barefoot running carries extra risk with PTTD

When you have posterior tibial tendon dysfunction, your posterior tibial tendon is already compromised. This tendon is responsible for supporting your arch and controlling pronation (the inward roll of your foot when you land).

Here’s why going barefoot can be problematic:

Reduced arch support: The posterior tibial tendon works harder without arch support from shoes. If the tendon is already inflamed or weakened, this extra load can slow healing or cause further damage.

Impact forces go directly to the tendon: Running shoes absorb some of the shock that would otherwise travel through your foot. Without that cushioning, more force reaches the posterior tibial tendon with each step.

Lack of motion control: Most running shoes offer some degree of pronation control. Barefoot running requires your tendons and muscles to do this work themselves, work your posterior tibial tendon may not be able to do if it’s already damaged.

Surface variability: When you run barefoot, you have less protection from uneven surfaces, rocks, and debris. Unexpected twists or sudden corrections can stress the tendon unexpectedly.

When barefoot running might be considered

That said, some people with well-managed PTTD do return to barefoot or minimalist running. Here are the conditions that would need to be met:

  • Complete symptom resolution: No pain, swelling, or tenderness along the tendon
  • Strong single-limb heel rise: You can perform at least 10 single-limb heel rises without pain
  • Normal arch appearance: Your arch maintains its shape when not bearing weight
  • Stage 1 PTTD only: Those with more advanced stages should avoid entirely
  • Permission from your doctor: Get explicit clearance from a podiatrist or sports medicine specialist

If you’re determined to try minimalist running, the transition must be extremely gradual (think months, not weeks).

How to transition safely (if approved)

If your healthcare provider gives you the green light, here’s how to approach it:

  1. Start with walking: Walk barefoot on soft surfaces for 10-15 minutes daily
  2. Add strides: After a week of walking, add 20-30 seconds of jogging, then walk
  3. Gradual mileage increase: Increase jogging time by 1-2 minutes per week max
  4. Listen to your body: Any return of pain means stop immediately
  5. Limit to soft surfaces: Grass, track, sand (never concrete)
  6. Keep sessions short: 10-15 minutes maximum to start

Safer alternatives to consider

If you’re looking for the benefits of barefoot running without the risks, consider these alternatives:

Minimalist shoes with some support: Shoes like Vivobarefoot or Merrell Vapor Glove offer some protection while allowing natural foot movement. Look for options with some arch support.

Zero-drop shoes with cushioning: These maintain the natural heel-to-toe offset of barefoot running while providing shock absorption. Brands like Altra offer this design.

Focus on foot strengthening: Before worrying about barefoot running, strengthen your feet with exercises like toe spreads, calf raises, and arch curls. A strong foot is more resilient.

Cross-training: Swimming, cycling, and elliptical training give you cardiovascular benefits without the impact stress on your posterior tibial tendon.

The bottom line

Barefoot running with PTTD is generally not recommended, especially in the early stages of recovery or with more advanced tendon damage. The risks (additional tendon stress, impact forces, and lack of support) outweigh the potential benefits for most people.

If you’re curious about minimalist running, talk to your podiatrist about whether it might be appropriate for your specific case. Even then, proceed with extreme caution and an extremely gradual transition.

Your posterior tibial tendon has been through enough. Give it the support it needs to heal properly.
