We know that people in countries with high levels of foot and ankle injuries don’t wear shoes, but why?
In a new book, the researchers at University of California, Berkeley, show why shoe use is declining in some places, even in countries where the number of people who wear shoes is still high.
The study looked at data on the global health of more than 13,000 people from around the world, who were tracked over a period of 15 years.
Their data is used to predict how many people will die of preventable diseases and injuries, and the percentage of people that wear shoes in the world.
Here are five facts you might not know about shoes: 1.
The number of Americans who wear them is dropping, and not because of any major pandemic.
Americans used to be the biggest users of shoes, according to a 2012 study.
But the number is down in every region, according the report.
In the Midwest, for example, shoes are less than half the number they were in 1999.
2.
Shoes are not a fashion accessory anymore.
In 2012, the average shoe cost $1,300 to make, according a report from Consumer Reports.
In 2014, the cost was $1.00.
A similar report from the British Medical Journal found that a pair of shoes costs less than $20 to make.
The shoes that cost the least are made in China, India, Japan and Taiwan, according Consumer Reports data.
3.
The shoe market is saturated.
The American market for footwear is dominated by companies that make products that are designed for a particular market.
This is the case with shoe brands such as Nike, Adidas and Under Armour, as well as shoes made by shoe brands like Clarks, Adidas Originals and Converse.
Shoes made in countries like Japan and China are also dominated by shoe companies like YSL, Adidas, Under Armour and Conseco.
The Japanese and Chinese shoe market accounts for nearly 60 percent of global shoe sales.
4.
The average person in America is using fewer shoes than ever.
The percentage of Americans that have worn a pair in the last 15 years has dropped from 51 percent in 1999 to 38 percent in 2014, according data from the US Census Bureau.
The reason for the drop is likely related to the global recession, which has made Americans more cautious about purchasing shoes.
In 2015, about 40 percent of Americans had never worn a shoe, according Census data.
The next closest people are those who have worn at least one pair of footwear in the past 15 years, at 26 percent.
5.
Footwear has become less expensive.
The cost of making a pair has dropped about 75 percent since the early 2000s.
In 2000, people paid $5 for a pair.
Today, it’s $3.00, according one report.
6.
People are more likely to wear sneakers in the summer than in winter.
The median annual cost of a pair is $80, according research from the Centers for Disease Control and Prevention.
This year, people are spending more time outdoors in the winter, which makes the average annual cost $90, according Healthways.
The survey of more 25,000 adults from November to March found that the average cost of shoes for the last two summers in the US were $60, according for the American Academy of Orthopaedic Surgeons.
In 2018, the median cost for a winter shoe was $50, according of the American Journal of Preventive Medicine.
7.
There’s a lot of foot traffic in the U.S. If you want to avoid the cold, walk outside during the summer.
In addition to the cost of winter shoes, people in the country are walking more and are using more outdoor gear in the warmer months.
The CDC reports that in 2019, the number for winter footwear was 11.5 million, compared to just under 4 million in 2014.
8.
The trend is for more Americans to walk outside in the cold.
In 2017, the CDC reported that about 22 percent of adults in the United States walked outside at least once a week.
In 2019, that number was more than 27 percent, according Data Science Journal.
9.
More Americans are walking indoors.
According to the CDC, about 27 percent of people in 2018 walked outside the home in the colder months.
In 2020, that rose to 40 percent, while in 2021 that climbed to 46 percent, the latest data from data company SmartBike shows.
10.
The rise of indoor fitness equipment is driving people outdoors.
In 2021, the percentage who walked outdoors in winter was about 11 percent.
In 2024, it was 12 percent, and in 2025, it increased to more than 16 percent.
11.
People who are outdoors have been getting older.
According the CDC data, the age of outdoor walkers dropped from 29.5 years in the 1960s to 26.9 years in 2019.
That is the lowest level since the 1930s.

The more we use outdoor equipment, the less of a
