How We Test & Compare Sneakers
Our methodology for size guides, cushioning comparisons, platform reviews, and resale valuations — so you know exactly how we arrive at our recommendations.
Size Guide Methodology
📏 How We Build Size Charts
Our size conversion data is sourced from official brand size charts, cross-referenced with community data from thousands of buyers on Reddit, YouTube reviews, and verified purchase reviews. Where brand charts conflict with real-world experience, we note both and explain the discrepancy. We update our charts when brands release new models with changed lasts.
👟 Fit Assessments (Wide/Narrow/True to Size)
Our true-to-size verdicts are based on aggregated buyer feedback from verified purchasers across major platforms including Zappos (which has detailed size feedback), Running Warehouse reviews, and direct community feedback. We weight feedback from buyers who specify their foot width and regular brand preference.
💰 Price Data
Resale prices in our guides are spot-checked across GOAT, StockX, and eBay at time of writing and updated periodically. Prices fluctuate daily — always verify current pricing on each platform before purchasing. Our Resale Cheat Sheet is updated monthly.
🛍️ Platform Comparisons
Our GOAT vs StockX vs eBay comparisons are based on direct fee structures published by each platform, buyer protection policies reviewed from each platform's terms of service, and community-reported authentication experiences. We do not receive payment from any platform for favorable coverage.
🦺 Comfort & Cushioning Assessments
For buying guides like Best Sneakers for Standing All Day, we rely on a combination of: verified purchase reviews from professional communities (nursing forums, teacher subreddits, retail worker groups), podiatrist recommendations where available, and technical specifications published by brands (midsole height, foam density, outsole construction).
What We Don't Do
- We don't accept paid placements or sponsored rankings
- We don't inflate affiliate partners' ratings
- We don't recommend products we wouldn't buy ourselves
- We don't publish size data without cross-referencing multiple sources
