Complete Asian to US Shoe Sizing Guide for SuperBuy Orders
Shoe sizing is the number one reason for returns and disappointment in the SuperBuy community. Asian manufacturers use their own size molds, which rarely align perfectly with US sizing standards. Worse, different factories interpret the same size chart differently. A Jordan 1 from one factory might fit like a true US 10, while the same labeled size from another factory fits like a 9.5. This guide teaches you how to measure, convert, and order with confidence.
How to Measure Your Feet Correctly
Stand on Paper
Place a blank sheet of paper on a hard floor. Stand on it with your full weight, wearing the socks you plan to use.
Mark Longest Points
Have someone mark the tip of your longest toe and the back of your heel. Do this for both feet — they may differ.
Measure in cm
Measure the distance between marks in centimeters. Round up to the nearest half centimeter.
Add Buffer
Add 0.5cm for a snug fit, 1.0cm for a comfortable fit. Use this final number when reading size charts.

Factory-Specific Sizing Quirks
Different factories cut their lasts — the molds shoes are built on — with subtle but meaningful differences. Some factories run long and narrow, others short and wide. The community tracks these quirks over time, and the information is usually available in Reddit QC threads or Discord sizing discussions. Always search "[batch name] sizing" before ordering a new silhouette from a factory you have not tried before.
Jordan 1 Reps
Most run half a size small. Order up 0.5 if you have normal feet, 1.0 if you have wide feet.
Dunk Reps
Generally true to size or slightly narrow. Wide-footers should size up 0.5.
Yeezy 350
Often run small by a half size. The Primeknit upper stretches, but the toe box is tight initially.
New Balance 9060
Tends to run true to size with a wider forefoot. One of the more consistent fits in reps.
Width Issues and Solutions
Width is the hidden sizing problem that length charts do not address. Many rep factories optimize for average Asian foot widths, which are narrower than average US foot widths. If you have wide feet, the standard advice to size up by 0.5 or 1.0 length applies, but it may not solve the width squeeze. For wide feet, look for community reports specifically mentioning width comfort. Some batches are known for being roomier in the toe box than others.
Frequently Asked Questions
Should I size up for all rep shoes?
Most rep shoes run small by 0.5 to 1.0 sizes, but it varies by factory and silhouette. Always check recent community feedback for the specific batch you are ordering.
Can I return shoes if the size is wrong?
Yes, if they are unworn and within the warehouse return window. However, return shipping to the seller is sometimes deducted from your refund.
What if my left and right foot are different sizes?
Measure both feet and use the larger measurement. It is better to have slightly more room in one shoe than to squeeze the larger foot.
Do insoles match the size chart exactly?
Not always. Some factories cut insoles slightly shorter than the stated size. Request an insole measurement photo in QC if you are between sizes.
