The people that buy $100+ shoes, boots, do it because they

1. Like it
2. Have the money for it
3. Want to be the first to wear it etc...........

It is just like buying rims for your car (why not stay stock), certain brand of aftermarket parts for your car (why not get your parts from autozone, or pepboys?), or something as simple as quality of the product. Why keeping on buying a $20 dollar boots from Target that will only last for two weeks? Just my thoughts.
