Learn about the latest technology of sports footwear and types of sports footwear. In addition, you will be able to understand the Concept of foot movements from the biomechanical point of view. Right type of footwear selection, Basic anatomy of foot and the sports shoes. After getting through the slides you will be in a position to get wide idea about the footwear and the importance of right footwear selection.

15. Why do we refer the foot rotation as
under Pronation / Hyper Pronation?
Pronation is the usual characteristic of
a complete gait
The regular gait has 13 degrees of
pronation (Clarke et al., 1984)
Pronation as the benchmark
Too much is over pronation.
Too less is Under pronation.

17. What is Pedobarography?
Study of pressure
between the foot surface and the
surface that supports.

19. 253 researches on foot biomechanics have been
published since 1981 until 2002 (21 Years) an average
of 13 publications per annum.
However, still the researchers are hunting for more
evidence in the field of foot biomechanics.

1989 first filed patent for pronation
control on 8th of November (Patent
Number: 5,046,267).
Nike was the first to get it patented.
21. Hyper pronation (excessive medial rotation of the
talus) may exist without Pes Planus (Gould N, 1983)
Forces acting on the foot during the stance phase act
as an input signal producing a muscle reaction.

Many physicians still abide by the rule
of changing your shoes every 300-500
miles.
