How we calculate
Every number on Manshoe is computed from price indexes published by the U.S. Bureau of Labor Statistics (BLS). A script reads the BLS Public Data API every night, checks the new values and rebuilds the site only if they pass. Nothing is typed in by hand.

Consumer price indexes (series starting CUUR and CUSR) are for all urban consumers, U.S. city average. Producer price indexes (WPU, PCU) follow prices received by U.S. producers; the shoe retailer index (PCU458210458210) measures retail margins. Import price indexes (EIU) measure prices paid to foreign sellers and exclude U.S. import duties.
The calculator
Value today = price paid × (index in the latest month) ÷ (average index in the year of purchase).
Example: a $60 pair of men’s shoes in 1995. The men’s footwear index averaged 134.417 in 1995 and stood at 161.769 in September 2026. $60 × 161.769 ÷ 134.417 = $72.21. The overall-inflation comparison uses the all-items index the same way.
We use annual averages for past years because most people remember the year of a purchase, not the month. For the current year we use the average of the months published so far. Men’s, women’s, and boys’ and girls’ indexes start in December 1977, so they cover purchases from 1978; the all-footwear index covers 1947 onward.
An index follows the price of comparable shoes over time, adjusting for changes in quality and in the shoes stores carry. The answer is therefore what a typical pair like yours would cost, not the current price of the same model.
Annual averages and the October 2025 gap
Annual averages are the mean of the twelve monthly values. BLS did not collect October 2025 prices because of the federal government shutdown and published no October 2025 CPI, so our 2025 averages use the eleven published months, and twelve-month changes that would need October 2025 are left blank. See the BLS notice on the shutdown’s effect on the CPI.
Ranks, real prices and comparisons
- Yearly change: change between two annual averages. The current year compares the months published so far with the same months a year earlier.
- Rank: the position of a year’s change among all complete years in the series, largest increase first.
- Real price: the shoe index divided by the all-items index, so a falling real price means shoes got cheaper relative to everything else.
- Percentile: the share of all twelve-month changes in the series that were lower than the latest one.
- Head to head: both indexes rebased to 100 in the starting year; index levels are never compared directly, because an index level is not a price.
Seasonal pattern
For each month from 2015 on we divide the unadjusted index by its centered 12-month moving average, average the result for each calendar month and center the twelve values on zero. Months whose window includes October 2025 are skipped. We compute this ourselves because BLS publishes some footwear series without seasonal adjustment in some years.
Updates and checks
The nightly job requests the most recent years for all series in a single API call (six years in February and March, when BLS revises seasonally adjusted data). It refuses to publish if a core series is missing, too short or more than four months old, and keeps the previous data instead. Pages show the date and the latest month they use.
