The document discusses several studies that found additional cushioning in shoes can help reduce ankle sprains. One study of over 10,000 basketball players found that many players wearing shoes with air cushions in the heel had a lower risk of ankle sprains. Similarly, another study of two groups of 1,000 runners each found that the group receiving information on injury risk factors and ankle sprains had fewer injuries. Overall the document suggests that cushioning in shoes, through technologies like air cushions or insoles, can help protect against ankle sprains when engaging in sports.
