The Sam Vimes "Boots" theory of socioeconomic unfairness, often called simply the boots theory, is an economic theory that people in poverty have to buy cheap and subpar products that need to be replaced repeatedly, proving more expensive in the long run than more expensive items. The term was popularized by English fantasy writer Sir Terry Pratchett in his 1993 Discworld novel Men at Arms. In the novel, Sam Vimes, the captain of the Ankh-Morpork City Watch, illustrates the concept with the example of boots.

The theory has been cited with regard to analyses of the prices of boots, gas prices, and economic conditions in the United Kingdom. In 2022, Jack Monroe received permission from the Terry Pratchett estate to use the name Vimes Boots Index (VBI) for a price index that would measure the cost of the cheapest staple foods.

Conception 
In the Discworld series of novels by Terry Pratchett, Sam Vimes is the cynical but likable captain of the City Watch of the fictional city-state of Ankh-Morpork. In the 1993 novel Men at Arms, the second novel focusing on the City Watch through Vimes' perspective, Pratchett introduces the "Vimes 'Boots' theory of socioeconomic unfairness" through Vimes musing on how expensive it is to be poor:

In the New Statesman, Marc Burrows hypothesized Pratchett drew inspiration from Robert Tressell's 1914 novel The Ragged-Trousered Philanthropists. In the book Fashion in the Fairy Tale Tradition, Rebecca-Anne C. Do Rozario argued "shoes and economic autonomy are inexorably linked" in fairy tales, citing the Boots' theory as "particularly relevant" and "an insightful metaphor for inequality".

Examples 
Since the publication of Men at Arms, others have also made reference to the theory. In 2013, an 
article by the US ConsumerAffairs made reference to the theory in regard to purchasing items on credit, specifically regarding children's boots from the retailer Fingerhut; a $25 pair of boots, at the interest rates being offered, would cost $37 if purchased over seven months. In 2016, the left-wing blog Dorset Eye also ran an article discussing the theory, giving fuel poverty in the United Kingdom as an example of its application, citing a 2014 Office for National Statistics (ONS) report that those who pre-paid for electricity—who were most likely to be subject to fuel poverty—paid 8% more on their electricity bills than those who paid by direct debit.

In a 2020 discussion paper for the Social and Political Research Foundation, Sitara Srinivas used the theory to analyze how sustainable fashion is inaccessible compared to fast fashion. In an article titled "The Price of Poverty" published in Tribune Magazine in 2022, the theory was cited as explaining the economic predicament in the United Kingdom. Examples provided included the higher cost of renting compared to home ownership, higher interest rates for loans to impoverished people, the effects of food poverty on educational advancement, and healthcare costs.

Vimes Boots Index 

The estate of Pratchett, who died in 2015, permitted the use of the 'Vimes Boots' name by Jack Monroe in 2022 for a project to track the price of the cheapest staple foods.
