I was interested to read your recent feature on barefoot running (see HCM July 13, p38). Benno Nigg and Henrik Enders, from the Human Performance Laboratory at the University of Calgary, recently published an article entitled ‘Barefoot running – some critical considerations’ in the journal Footwear Science. This examined the known research into barefoot running’s effects on foot motion, training, running economy and injury.

Nigg and Enders dispute claims that running without shoes encourages a forefoot rather than a heel landing, making runners less prone to injury. They state that not only does the available research not prove any reduced injury risk, but also that other factors – such as the running surface, shoe choice, speed and individual preferences – play too large a role to make such generalisations possible. Likewise, the researchers found no difference between shod and barefoot movements in their ability to strengthen certain muscles.

They also question the main claim of barefoot supporters: that running without shoes leads to fewer injuries. They point to problems with the research on which the original claims were based and note that, while existing articles address the different injuries caused by different landing styles, they know of “no publication that provides hard evidence that people running barefoot have fewer injuries than people running in running shoes”. They conclude that “it is not known whether people running barefoot have more, equal, or fewer injuries than people running in conventional running shoes”.

When it comes to performance and injury, Nigg and Enders suggest that individual preference and running style is what matters: in the end, runners run best when they’re comfortable – whatever they’re wearing (or not) on their feet.
