What is SneakPrice and how does it work?+
SneakPrice is a sneaker market intelligence platform that turns the chaotic world of resale into clear, actionable data. With support for 21 international languages and the Sneaker Stock Exchange — a Bloomberg-style live market view of the entire global sneaker economy — it pulls real listings from eBay, StockX, GOAT, Stadium Goods and other major marketplaces in real time, then normalizes them into a single market price for every model we track.
Behind the scenes:
• Our computer-vision model identifies the sneaker from a photo or live camera frame.
• Our market engine scans live listings across every major resale platform.
• We calculate an average resale price, trend direction, volatility, and a liquidity score.
• Our arbitrage engine flags cross-platform price gaps so you can buy low and sell high.
• The Sneaker Stock Exchange aggregates everything into brand indexes (SPX-NIKE, SPX-ADIDAS, SPX-JORDAN, etc.) and a master SPX-RETRO benchmark, so you can track the market the way traders track the S&P 500.
For the Cortez, this means you see the real resale value — not a guess, not a single marketplace's number, but a true cross-market average updated continuously.
How do I get started with SneakPrice?+
Getting started is simple:
1. Sign up at https://sneakpriceapp.com — free, no credit card required.
2. From the home page, scan a sneaker. You can use your camera in real time, upload a photo from your gallery, or paste an image URL. The app will identify the model automatically (including the Cortez and over 1,000 other catalog entries).
3. Instantly see the market report: average resale price, trend direction, comparable listings, retail vs. resale delta, and a flip score.
4. Save sneakers to your portfolio, set price alerts, and explore the Sneaker Stock Exchange for live indexes and arbitrage deals.
5. Upgrade only when you want more — the free tier covers the basics for life.
What can I use SneakPrice for?+
SneakPrice is built for everyone in the sneaker ecosystem:
• Buyers: Confirm a listing isn't overpriced before clicking "buy now". See average resale across every major platform side-by-side.
• Resellers & flippers: See real-time average resale, demand, volatility, and liquidity before listing. Our flip score tells you if a pair is worth the capital tie-up.
• Collectors: Track your collection's mark-to-market value and individual pair appreciation over time. Get notified when grails move.
• Arbitrage traders: Our deal engine surfaces cross-platform price gaps — buy on eBay at $180, sell on StockX at $260, for example.
• Authenticators: Cross-reference suspicious "deals" against real market ranges. If a Cortez is listed at 40% below market, something is usually wrong.
• Market researchers & journalists: Pull historical price trends, brand indexes (SPX-*), and category-level signals.
• Casual fans: Just curious what your old pair is worth? Scan it in 5 seconds.
Do I need technical skills to use SneakPrice?+
Not at all! SneakPrice is designed for everyone — collectors, casual buyers, full-time resellers, and first-time sneaker fans. If you can take a photo or open a web page, you can use it. Our AI identifies the sneaker for you, our market engine pulls live prices for you, and our Stock Exchange dashboards visualize the data with zero spreadsheet work.
Deeper analytics (alerts, portfolio tracking, arbitrage deals, the SPX brand indexes) are one click away when you're ready for them — but you can ignore them entirely and still get the full value of instant market pricing.
If a sneaker identification is not accurate, what should I do?+
Our vision model recognizes 60+ classes and over 1,000 catalog entries, but no AI is perfect — especially with extreme lighting, partial views, or rare collaborations. If a Cortez (or any sneaker) is misidentified, here's what to do:
1. Re-take the photo: a clean side profile on a neutral background lifts accuracy dramatically. Avoid harsh shadows and try to capture the full silhouette.
2. Use the manual override: every scan result has a "Wrong sneaker?" link that lets you search our catalog and correct the match. Your correction is saved to your scan history and feeds back into our training data so the model improves over time.
3. Search directly: if you already know the model, skip the scan and use the search bar at the top of the site — it indexes every entry in the Sneaker Encyclopedia.
4. Report the miss: use the contact form at https://sneakpriceapp.com/contact and include the photo. Reports go directly into our retraining queue.
Every correction makes the model better for the entire community.
How do I delete unwanted pictures from the sneaker app?+
You're always in full control of your photos and scan history:
• To delete a single scan: open your scan history, tap the scan, and use the "Delete" button. The photo and its metadata are removed immediately.
• To bulk-delete: from your dashboard, select multiple scans and use "Delete selected".
• To wipe everything: under Settings → Privacy, you'll find "Delete all scans" and "Delete account". Both are irreversible and execute immediately.
• Photos uploaded by mistake (wrong sneaker, blurry shot) can be removed instantly — they're never shared publicly and only used for your own market reports.
Deleted photos are purged from our storage layer, not just hidden. We don't retain shadow copies. If you'd like a confirmation, contact us at https://sneakpriceapp.com/contact and we'll send written confirmation of the deletion.
Does SneakPrice accept newly-taken sneaker pictures or camera photos as well?+
Yes — both. SneakPrice accepts three input methods, and they all feed the same vision pipeline and market engine:
1. Live camera: Open the scanner and point your phone or webcam at the sneaker. The app identifies the model in real time and pulls live market data within seconds. Works directly in your browser — no app install required.
2. Photo upload: Tap "Upload photo" and pick any image from your camera roll or device storage. JPG, PNG, HEIC, and WEBP are all supported.
3. Image URL paste: If you saw a Cortez on Instagram or a marketplace listing, paste the image URL into the scanner and we'll fetch it for you.
Important — file size limit: uploaded images must be 2 MB or smaller. Modern phones often produce 4–10 MB photos by default, which the scanner will reject with an error. If you see an upload error, resize or compress the image first. Easy ways to do this:
• iPhone: open the photo in Mail, attach it, and choose "Medium" or "Small" — Mail will compress to well under 2 MB.
• Android: most gallery apps have a "Resize" option, or use a free compressor app.
• Desktop: drag the image into a free web compressor (e.g., tinypng.com or squoosh.app) and download the smaller version.
• Or simply screenshot the original photo — screenshots are typically well under 2 MB.
Tip for best accuracy: a clean side profile with the toe pointing left or right dramatically improves identification — especially for nuanced colorways.
How accurate are the prices SneakPrice shows for the Cortez?+
Our prices are sourced from live listings across eBay, StockX, GOAT, Stadium Goods, and several other major resale platforms — not estimates or static price tags. For each model we compute:
• Average resale: the mean of recent comparable listings, filtered for outliers.
• Trend (7d, 30d, 90d): direction and magnitude of price movement.
• Volatility: how much prices swing — important for flip-risk modeling.
• Liquidity: how many recent comps exist — a single overpriced listing doesn't move the number.
• Flip score: combines all of the above into a single buy/hold/sell signal.
Refresh cadence varies by tier: free users see daily-refreshed data; paid users see near-real-time updates. For ultra-rare or recently-released Nike pairs with thin comp data, we flag the result as "low confidence" rather than fabricate a number.
Can I track my Nike collection as a portfolio?+
Yes. Every scanned or manually-added pair can be saved to your portfolio, complete with purchase price, condition, and acquisition date. From there you get:
• Mark-to-market valuation: every pair re-priced continuously against live market data.
• Unrealized P&L: per-pair and total — both in dollars and percent.
• Allocation breakdown: how your collection splits across brands, eras, and tiers.
• Index comparison: see if your portfolio is outperforming SPX-NIKE, SPX-RETRO, or the broader sneaker market.
• Exit signals: alerts when a pair crosses a price threshold or our flip score flips from "hold" to "sell".
Your portfolio is private by default. Sharing is opt-in if you ever want to show off your collection.
What is the Sneaker Stock Exchange?+
The Sneaker Stock Exchange (/exchange) is a Bloomberg-style live market view of the entire global sneaker resale economy. It features:
• SPX brand indexes — SPX-NIKE, SPX-ADIDAS, SPX-JORDAN, SPX-NEW-BALANCE, SPX-ASICS, SPX-PUMA, SPX-CONVERSE, SPX-SAUCONY, SPX-VANS — each tracking the weighted average resale price of that brand's most-traded models.
• SPX-RETRO — our master benchmark covering the broader retro and heritage market.
• Price-band indexes — track the entry, mid, and premium tiers separately.
• Live arbitrage feed — cross-platform deals flagged the moment they appear.
• Heatmaps, gainers/losers, and volume leaders.
Think of it as the financial-market view of sneakers: you're not just seeing one pair, you're seeing the entire ecosystem in motion.
