Shoes are the most-ordered category on the oopbuy spreadsheet. This guide is a drop calendar and sizing map — when silhouettes hit the sheet, when to buy which family, and how sizing actually maps across Asian and US charts.
Part 1: The 2026 drop calendar
Approximate windows when new sneaker silhouettes have historically appeared on the sheet:
- January-February: retro runner refreshes ahead of spring launches. Vintage colorways dominate.
- March-April: chunky trainer restocks. New tech-runner silhouettes appear.
- May-June: summer low-top skate season. Canvas and suede dominate.
- July-August: mid-year basketball retros. 90s and 2000s throwbacks peak.
- September-October: autumn/winter mid-cuts. Leather and hybrid silhouettes appear.
- November-December: holiday exclusive colorways. Rare drops, high hype.
Part 2: The four silhouette families
Retro runners
Sizing: true to size on most Asian charts. Trust the label.
QC coverage: deepest of any family. Popular listings have 30+ photos.
Reject rate: 5-7% community-wide.
Best for: first sneaker order. Safest family.
Chunky trainers
Sizing: runs a half size wide. Size down if between sizes.
QC coverage: strong on popular colorways.
Reject rate: 8-12%.
Best for: second sneaker order once you know Asian sizing.

Low-top skate silhouettes
Sizing: runs narrow, especially toe box. Wide-footed buyers size up.
QC coverage: mid-depth.
Reject rate: 6-9%.
Best for: summer parcels.
Basketball retros
Sizing: varies by decade of original. 90s runs large, 2000s runs true, current-season runs narrow.
QC coverage: deep on established, thin on brand-new releases.
Reject rate: 10-15% — widest of any family.
Best for: patient buyers who wait 4+ weeks post-drop for community QC to accumulate.
Part 3: The sizing map
Reference sizing math for a US 10 buyer:
- Retro runners: order label US 10.5 or EU 44.5.
- Chunky trainers: order label US 9.5 or EU 43 (silhouettes run wide).
- Low-top skate: order label US 10.5, size up if wide-footed to US 11.
- Basketball retros 90s era: order label US 10.
- Basketball retros 2000s+ era: order label US 10.5.
Always verify against the seller measurement chart. Labels lie; charts do not.
Part 4: The buying workflow
- Check the drop calendar for the current window.
- Open the oopbuy shoes sheet.
- Filter to your target silhouette family.
- Verify community QC block has 15+ photos.
- Cross-check sizing chart against silhouette family adjustments above.
- Apply the four-axis QC inspection (toe box, outsole, colorway, insole branding).
- Cart and bundle with 2-3 other items to hit shipping economy.
Cost expectations
- Retro runners: US$60-100 per pair.
- Chunky trainers: US$80-130 per pair.
- Low-top skate: US$50-85 per pair.
- Basketball retros: US$70-140 per pair depending on release.
The one mistake to avoid
Do not ship a single pair alone. Single-pair parcels waste 40% of shipping economies. Always bundle sneakers with 2-3 other items to hit the 1.2-3 kg parcel sweet spot. See consolidation guide.

Which silhouette family is the safest?
Retro runners. Simple construction, mature factory tooling, wide QC coverage. Reject rates around 5-7 percent, lowest of any sneaker family.
What is the sizing math?
Asian sizing runs about half a size below US on average. Adjust per silhouette family u2014 chunky runs wide, low-top skate runs narrow. Match against seller measurement chart not label.
