A $50 pair of men’s shoes bought in 1990 works out to about $64.95 as of September 2026 if you adjust it with the Bureau of Labor Statistics (BLS) index for men’s footwear, and to about $128.94 if you adjust it with the all-items Consumer Price Index. Both figures are arithmetically correct. They answer two different questions, and mixing them up is the most frequent mistake people make when they bring an old shoe price forward.
Two indexes, two questions
The all-items Consumer Price Index (CPI) follows the prices of everything urban households buy, from rent and groceries to car insurance. The BLS describes the series behind its own online calculator as the CPI for All Urban Consumers, U.S. city average, all items, not seasonally adjusted. The men’s shoe index follows only the price of men’s shoes. Over long stretches these two lines have moved very differently, so the choice of index decides the answer.
Ask yourself which of these you want to know:
- What would a comparable pair cost now? Use the shoe index. It tells you how the price of that kind of product changed.
- How much spending power did that money represent? Use the all-items CPI. It tells you what the same dollars would buy across the whole economy.
If an old catalog lists men’s oxfords at $50 and you want to know whether shoes really were “cheaper back then”, the shoe index is the honest yardstick. If a family story says someone spent $50 on shoes in 1990 and you want to know how big a purchase that was for the household, the all-items figure is closer to the point.
The gap between the two answers is itself a finding. Measured against all items, men’s shoes in September 2026 cost about half what they did in 1990, relative to everything else: the men’s shoe index divided by the all-items CPI is 49.6% lower than its 1990 average. That ratio is charted year by year on the shoes against all prices page.
The calculation, step by step
Our calculator uses one formula: value now = old price × (index in the latest month) ÷ (annual average index of the purchase year). With men’s shoes and a 1990 purchase:
- The 1990 annual average of the men’s shoe index (series CUUR0000SEAE01) is 124.533.
- The September 2026 value is 161.769.
- $50 × 161.769 ÷ 124.533 = $64.95.
The all-items version uses the same steps with different inputs. The 1990 average is 130.658, September 2026 is 336.94, and $50 becomes $128.94.
Worked examples for 1990 and 2005
| $50 paid in | Men’s shoe index result | All-items CPI result |
|---|---|---|
| 1990 | $64.95 | $128.94 |
| 2005 | $66.66 | $86.27 |
The 2005 row looks odd at first. The shoe-adjusted value of a 2005 purchase is higher than that of a 1990 purchase, even though 2005 is more recent. The reason is in the data: the men’s shoe index averaged 121.342 in 2005, about 2.6% below its 1990 average of 124.533. Men’s shoe prices drifted down for part of that period, so a dollar spent on shoes in 2005 bought slightly more shoe than a dollar in 1990. The all-items CPI rose steadily over the same years, which is why its 2005 answer is much smaller than its 1990 answer.
The category also matters. The same $50 spent in 1990 comes to $64.24 with the women’s shoe index, $69.86 with the boys’ and girls’ index and $65.82 with the index for all footwear. You can see each category’s full history on the men’s shoes page and its sister pages, and the 1990 price page lists every category for that year.
Annual average or a single month
Most old receipts and catalogs give a year but not a month, so our calculator divides by the annual average of the purchase year. The BLS notes in its CPI FAQ that annual averages “reduce volatility by smoothing out the highs and lows” of monthly data.
If you do know the month, the result shifts a little. For a $50 pair of men’s shoes:
- bought in January 1990 (index 122.5), the value as of September 2026 is $66.03;
- bought in December 1990 (index 125.6), it is $64.40.
With all items, January 1990 (127.4) gives $132.24 and December 1990 (133.8) gives $125.91. The spread within one year is small next to the gap between the shoe index and the all-items CPI, so using the annual average rarely changes the conclusion.
Two data details affect recent years. The BLS could not collect October 2025 CPI data because of the lapse in federal appropriations, and its own calculator page states that calculations using October 2025 data will not be calculated. Our 2025 annual averages therefore use the 11 months that were published. For a purchase made in 2026, we divide by the year-to-date average; for men’s shoes that average is 156.826 for January through September, so $50 spent this year comes to $51.58.
Where the method stops working
An index converts a price faithfully only when the thing being priced stays comparable. Several limits apply to old shoe prices.
Quality and model changes. When a product in the CPI sample changes, the BLS FAQ explains that “a new item is selected or the quality change in the current item is recorded”, and that its commodity specialists try to keep quality changes from being counted as price change. The index therefore follows comparable shoes over time. Your particular pair, or a brand that has moved up or down market since 1990, can sit far from the category average.
It is not a full cost-of-living measure. The BLS Handbook of Methods says the CPI “only approximates a cost-of-living index” and calls it a conditional one, because many things that affect living costs never pass through a market transaction. An all-items adjustment shows price change, not how well off a household felt.
National average, urban population. The CPI-U reflects the spending patterns of urban consumers who, per the Handbook, represent over 90 percent of the U.S. population. A small-town store in 1985 or a factory outlet price may not match the national figure.
Series start dates. The men’s, women’s and boys’ and girls’ shoe indexes begin in 1978 on our site. For an older price, the only footwear option is the all footwear index, which goes back to 1947.
A sale price is still a price. A receipt shows what was paid that day. If the pair was marked down, the converted figure describes the marked-down price, not the regular one.
A short routine for any old price
- Write down the price, the year and, if known, the month.
- Pick the category that matches the shoe: men’s, women’s, boys’ and girls’, or all footwear for pre-1978 prices.
- Run the shoe index result first. That answers “what would a similar pair cost now”.
- Run the all-items result if you also want the general spending-power comparison.
- Report both numbers with the date of the latest index, for example “as of September 2026”, since the figures update each month.
