How we work
A weekly observational sample of footwear offers from stores classified as retail in our inventory ledger, available to US shoppers in USD. Product condition is not independently verified; the sample may include new, pre-owned and resale stock. Only ledger offers verified within 60 minutes of capture, marked in stock, with explicit prices for available sizes are included. Each listed size is at least 10% below the retail benchmark recorded in Grail Call's shoe catalog. That benchmark is not a claim about the retailer's previous selling price. Sizes retain the retailer's labels; US, UK, EU, men's, women's and youth sizes are not assumed equivalent. Shipping, tax, coupons, offers classified as resale in the ledger and unknown prices are excluded. The ledger classification does not establish that every included offer is new or non-resale. Duplicate style codes and store product URLs are counted once. At least 10 style codes across two stores are required to publish. Coverage is limited to catalog shoes matched to the inventory ledger, not the entire sneaker market. This is not a popularity ranking or a representative market survey.
