This is a summary essentially:
Beginner shoes: Flat, sturdy, low asymmetry
Intermediate shoes: Increased asymmetry, slight arch
Expert shoes: High asymmetry, pronounced arch and downturn
What is asymmetry?
High asymmetry is uncomfortable and you probably don't want to start yourself off that right off from the bat!
What is the deal with lined and unlined shoes?
Special note: Leather shoes tend to stretch more! You'll also want to pay attention to the tech specs of the shoes you're buying. La sportiva has a material sewn into their higher end shoes known as Lorica that basically prevents stretching. Other things like P3 helps to maintain the shape of the downturn over long periods of time. This is important for an aggressive shoe.
Velcro, Lace, Moccasins?

Found a great resource on youtube and he shows you how he washes his shoes in the washer!
Important note: Do not place your shoes in the dryer! Also, do not wash leather shoes! They will dry up and crack. It reduces the lifespan of your shoe. Also, if you wear them when they are wet, they'll expand and get bigger. So that's another way of stretching out your shoes if you want them to be stretch. But if you don't, keep those leather shoes dry.
