Shoe Doctor : Interactive Running Shoe Wear Pattern Analyzer
Shoe Doctor: Wear Pattern Analyzer
Your used running shoes record your gait mechanics. Follow the 3 simple checks below to identify overpronation, supination, or neutral gait.
1 Check Your Outsole Wear
What to look for: Turn your right shoe upside down. Identify where the rubber tread pattern is ground down or worn smooth to the foam.
Outer Heel + Toe
Neutral Heel Strike
Ball of Foot
Mid/Forefoot Landing
Inside Edge
Overpronation (Roll In)
Outside Edge
Supination (Outer Ridge)
2 Table Tilt Test
How to test: Set your used shoes on a flat table at eye level. View them directly from behind the heel counter to see if they lean.
Tilts Inward
Heels angle together
Sits Straight
Upright alignment
Tilts Outward
Heels angle outward

Gait Diagnosis
Good Condition
Neutral Mechanics
Your wear pattern indicates a balanced landing. You land on the outer heel and roll naturally to the center of the forefoot for push-off.

Frequently Asked Questions (FAQs)
What is running shoe wear pattern analysis?
Running shoe wear pattern analysis is the practice of examining the outsole (bottom rubber) of a used shoe to understand a runner’s unique biomechanics.
When you run, friction occurs between your shoe and the ground. Over time, this friction erodes the rubber in specific areas based on how your foot lands, absorbs shock, and pushes off. By “reading” these high-wear zones, you can identify your gait type:
Neutral gait: Wear is typically seen on the outer heel (landing) and the center of the forefoot (push-off).
Overpronation: Excessive wear on the inner (medial) edge of the shoe, indicating the foot rolls inward too much.
Supination (underpronation): Excessive wear on the outer (lateral) edge, indicating the foot does not roll inward enough to absorb shock.
This analysis helps runners choose the correct type of shoe (neutral, stability, or motion control) to prevent common injuries.
What is the difference between shoe wear on the inside vs. the outside?
Wear on the outside (lateral side) typically indicates supination (underpronation) or a neutral heel strike. Wear on the inside (medial side), particularly near the ball of the foot and big toe, typically indicates overpronation, where the foot collapses inward excessively during the stride.
Can looking at my old running shoes tell me how I run?
Yes. Your running shoes act like a recording device for your gait. The specific areas where the rubber is worn down (wear pattern) combined with the angle at which the heel leans (tilt test) can reveal if you are a neutral runner, an overpronator, or a supinator.
How many miles do running shoes last before the wear pattern becomes unreliable?
Most running shoes last between 300 and 500 miles before they need to be replaced. Analyzing shoes with very low mileage (under 100 miles) may yield inconclusive results because the wear pattern hasn’t fully developed. Conversely, analyzing shoes with over 600 miles might show “false” wear simply due to material breakdown rather than biomechanics.
Does a neutral wear pattern mean I don't need stability shoes?
Generally, yes. A neutral wear pattern (wear on the outer heel and center forefoot) usually suggests you have efficient shock absorption and should run in neutral cushioning shoes. However, if you experience fatigue-related injuries, you might still benefit from “stable neutral” shoes that offer mild guidance without aggressive correction.
Can I use this wear pattern analysis for walking shoes?
Yes, but with caveats. While the mechanics of walking and running differ (walking has a distinct “double support” phase), the general wear patterns for overpronation (inner edge) and supination (outer edge) remain consistent. However, the severity of wear on walking shoes accumulates much slower than on running shoes.
Note: The Shoe Doctor is a guidance tool based on general running shoe wear patterns. It is not a medical diagnosis. If you are experiencing persistent pain, discomfort, or injury, please stop running and consult a certified medical professional or sports podiatrist for a comprehensive gait analysis.
