I made an important discovering yesterday.
Its about running shoes.
Sometimes I go to a running shoe store and spend $120+ on running shoes, even though I don't run.
Other times I buy them for half the price online.
I usually switch between Asics and Mizuno. No particular reason other than the sales people at the running stores usually tell me to buy one of those pairs.
I also have to buy narrows, 2A.
In an Asics I'm a 2A 10
In Mizuno, I'm a 2A 10.5
That explains why for the last year and half I've been wearing shoes too big for me and why I'm now returning shoes that are too small for me. Their sizing is different.
