as it turns out, today is actually thursday.

bad news: i will not buying new shoes today, as i don't get checks until tomorrow.
good news: i don't have to work at blackbird, so i can play oblivion all night. (!!!)

tomorrow i buy running shoes.

from runners world:

"Pronation is the inward (medial) roll of the foot and in particular the heel and arch which occurs naturally at the heel strike as a cushioning mechanism.

Overpronation is when the feet roll inward too much.

Supination, also known as underpronation, is the opposite to pronation where the feet don't roll inward enough. Wearing the wrong type of shoe will lead to painful shins and joints, or even injury.

A pronator's outer soles wear down along the inside of the ball of the foot and they tend to have flat feet.
The supinator's outer soles wear down along the outer edge and their feet tend to have high arches. Shoes are designed with features to control these problems."

this is helpful info.
