Running Shoes 
With so many different running shoes on the market, it can be
difficult to determine which type of shoe you need. Runner's feet come in three
styles:
- Pronator (with the heel on the ground the medial arch is close
to the ground)
- Supinator (with the heel on the ground the medial arch is
lifted away from the ground)
- Neutral
What is Pronation?
Pronation refers to the inward roll of the foot during
normal motion and occurs as the outer edge of the heal strikes the ground and
the foot rolls inward and flattens out. A moderate amount of pronation is
required for the foot to function properly, however damage and injury can occur
during excessive pronation. When excessive pronation does occur the foot arch
flattens out and stretches the muscles, tendons and ligaments underneath the
foot. The picture right shows a view of the right foot as if looking at it from
behind. As you can see in the picture the ankle is over pronating or rolling
inwardly. |

What is Supination?
Supination is the opposite of pronation and refers to the
outward roll of the foot during normal motion. A natural amount of supination
occurs during the push-off phase of the running gait as the heal lifts off the
ground and the forefoot and toes are used to propel the body forward. However,
excessive supination (outward rolling) places a large strain on the muscles and
tendons that stabilize the ankle, and can lead to the ankle rolling completely
over, resulting in an ankle sprain or total ligament rupture. This time, in the
second picture right, the foot is over supinating or rolling outwardly. |

How do you determine your style?
If you have an old pair of running shoes place them on a flat
surface. If they lean outwards from each other then you are a supinator, if
they lean inwards a pronator otherwise you are neutral. Alternatively walk on a
tiled floor with wet feet. If the width of the wet strip connecting the heel to
the toes is more than half the foot width then you are a pronator, less than
half the width a supinator otherwise you are neutral.
Type of shoes
The shoe types available are:
- Motion control
- Cushion/motion control
- Support
- Cushion
- Lightweight/supportive
- Lightweight
- Racer/supportive
- Racer
- Trail
In choosing your running shoes, you also need to take into
consideration your weight and the type of running you will be doing:
- Steady road running
- Fast road running
- Road racing
- Road and trail running
Advise
If you foot type is supinator or pronator and you have a coach,
ask them to look at the way you run. Some athletes may need inserts in their
shoes to correct over pronation and may need a gait assessment by a podiatrist
(foot specialist).
Rules for Track Shoes
IAAF Competition Rules 142 states:
- The sole and heel of the shoes shall be so constructed as to
provide for the use of up to 11 spikes. Any number of spikes up to 11 may be
used but the number of spike positions shall not exceed 11.
- When a competition is conducted on a synthetic surface, that
part of each spike that projects from the sole or the heel shall not exceed 9mm
except in the high jump and javelin throw events where it shall not exceed
12mm. These spikes shall have a maximum diameter of 4mm.
- For the non-synthetic surfaces, the maximum length of spike
shall be 25mm and the maximum diameter 4mm.
- The sole and/or heel may have grooves, ridges, indentations or
protuberances, provided these features are constructed of the same or similar
material to the basic sole itself. In the high jump and long jump, the sole
shall have a maximum thickness of 13mm and the heel in high jump shall have a
maximum thickness of 19mm. In all other events the sole and/or heel may be of
any thickness.
Shoe Care
To reduce damage to your running shoes:
- Only wear them for running and do not use for playing other sports
- Undo the laces before removing the shoes
- Avoid running in wet shoes
- Do not wash them in the washing machine
- Do not expose to excessive heat - let them dry naturally
Shoe Life
- The midsole material in most running shoes may lose 30-50% of their shock absorption after approx. 250 miles of use - consider replacing your shoes after 500 miles of use
