During a lifetime, a human being will walk around 185,000 km, which is enough to circle the earth four times! This averages out at 10,000 steps a day. Of course, some people will walk greater distances that others.
Despite being relatively small in themselves, feet account for a massive 25% of the number of bones in a human body. A foot contains 26 bones, 33 joints, 107 ligaments and 19 muscles. There's plenty to go wrong if they aren't adequately protected.
There are around 250,000 sweat glands in a pair of human feet. These can produce up to half a pint (200 ml) of sweat a day.
When running, the pressure on feet can be up to four times the runner's body weight.
Fingernails and toenails grow more rapidly in warm weather, as well as during pregnancy and adolescence.
As many as nine in every ten women in the developed world, wear shoes that are too small for them.
Statistically, women have four times as many foot problems as men, with high heels partly to blame.
Even though shoes can cause you foot trouble, be extra careful when going barefoot. Places such as communal showers can be a hotbed of nasty diseases like athlete's foot, plantar warts and ringworm.In developing countries, a lack of shoes can leave people vulnerable to all manner of soil-transmitted diseases and parasites, from hookworm and jiggers to podoconiosis and the potentially fatal tetanus.
