Complete Testing Methodology
This page documents exactly how every walking shoe gets tested before it earns a review on CoolWalking. It is here so that anyone โ a reader, another reviewer, or a brand โ can reproduce what we do and check for themselves.
The One-Sentence Summary
If a shoe hasn't been walked in for at least 500 kilometers on a mix of pavement, park, and trail surfaces, it doesn't get reviewed. Everything else on this page is just the details behind that one rule.
Step 1: Purchase At Retail
Every shoe is purchased at full retail price. No sponsored units, no PR samples, no discounted "media" copies. This is why the reviews are slow โ testing is a personal expense.
Step 2: Baseline Walk (0-50 km)
The first 50 kilometers are the adjustment period. This is where the shoe breaks in, where blisters either appear or don't, and where I note the initial feel: heel lock, forefoot flex, midsole firmness. Notes are taken every 10km.
Step 3: Surface Split (50-300 km)
Kilometers 50-300 are split roughly as follows:
- 60% city pavement
- 25% park / soft trail
- 15% mixed / gravel / hillside
This matches how a normal person actually walks. It is not a lab setting.
Step 4: Buffer Decay Tracking (300-500 km)
Between 300km and 500km, the shoe is checked for midsole compression, heel wear pattern, and outsole tread loss. Every 50km, a fresh set of notes is recorded in the buffer decay log โ the raw data behind the reviews.
Step 5: The 500km Verdict
At exactly 500km, the shoe is given a full written verdict. The verdict includes what worked, what failed, who should buy it, and who should not. This is what you read as a review.
What We Don't Do
- We don't run lab tests. No compression machines, no force plates.
- We don't publish "first week" impressions as reviews.
- We don't accept sponsored samples.
- We don't pretend a shoe is good because it's expensive.
