Over and Underpronation.

 Never used to think about these things. But recently , a friend checked my worn out shoes and said I may be 'overpronating' . Which in itself is not bad , but may need special care (in terms of better shoes).

i did some research and here is how the wear pattern of an over and under pronator woud look like.

If you are facing shin-splints or other pains, and not sure why, this may be a good thing to check for.

Motion control shoes - these are very rigid and provide extra stability. Ideal for flat-foot and for overpronation.  Very sturdy .

Stabilizer shoes: very less sturdy. For high-arch. lighter and good for races. When you bend the shoe it easily bends.
