INDIVIDUAL'S
RUNNING STYLE (i.e. over pronation)
|
| |
 |
Normal
pronation is when the heel lands on the outside, the foot
rolls until the heel is aligned under your lower leg. Then the
foot becomes rigid and propels you forward |
| |
|
|
| |
 |
Overpronation
is when the foot rolls in too far after it hits the ground or
before it prepares for the push-off. |
| |
|
|
| |
 |
Underpronation
(or supination) is when the foot rolls to the outside after
hitting the ground. Only 10% of the population are underpronators.
This type of foot doesn't absorb shocks really well. |
