00:00 They are covered with a special skin, without hair and full of nerve endings.
00:06 That's why we feel so bad when we hurt our feet.
00:10 Yet, they are not as delicate as we think.
00:13 The structure of our feet is incredible in itself.
00:17 They are made up of 26 bones, 33 joints and more than a hundred muscles, tendons and other ligaments.
00:25 These elements work together like a machine that allows us to move.
00:30 When we run, our feet work like springs.
00:33 They must support up to seven times the weight of our body each time they touch the ground.
00:38 Thanks to a savant arrangement of ligaments, tendons and muscle tissue,
00:43 our feet hold and return to the ground a large part of this force.
00:48 In addition, they can also give us indications of our general health.
