1. The Lapps wear boots without heels whereas we do the opposite. We can see that dancing masters and tightrope walkers use low heels or no heels at all and perform very rapid feats that they would be unable to perform in shoes with heels. Other people who move quickly, such as runners and foreigners, do the same. On the other hand, those who wear large and high heels walk deliberately and heavily. If we want horses to have a steady gait, we put heavy shoes on them while they are still young. And if farm-lads down in the south want to run, they take their shoes off. For heels remove half the control from the muscles of the sole of the foot. High heels and little exercise also cause the muscles to grow stiffer; a man with a wooden leg walks heavily.
