The Most Common QC Mistakes
After reviewing thousands of QC submissions, we have identified the most common mistakes that lead to disappointment. Avoiding these pitfalls will save you money and frustration.
The number one mistake is comparing your QC to marketing photos rather than retail reference photos. Marketing photos are heavily edited and often do not represent real products accurately.
Mistakes That Cost You Money
These mistakes either lead to accepting bad products or returning good ones unnecessarily:
| Mistake | Why It Hurts | How to Fix |
|---|---|---|
| Comparing to stock photos | Unrealistic expectations | Use retail reference photos from r/Sneakers or similar |
| Ignoring batch flaws | You accept known issues | Research current batch problems on Reddit |
| Over-analyzing minor stitching | You RL good products | Focus on visible flaws, not microscope details |
| Not checking sizing | Wrong fit on arrival | Always compare insole measurements to your shoes |
Expert QC Tips
Experienced buyers focus on three things: overall shape accuracy, color correctness under natural lighting, and material quality that matches retail. They use natural daylight photos as references rather than studio lighting.
Always check the insole measurement against your best-fitting shoe. Size charts are not consistent across sellers, and a size 10 from one factory may fit completely differently from another.
