HanesWomen's 6-Pair Lightweight Breathable Ventilation Ankle Socks

So if I wear a shoe size 8, I should order 8-12? Not shoe size 5-9?

What size should I get for a size 8 shoe?

do these socks start having a 'fuzzy' look to the material after several wearings? im looking for ones that keep the smooth look to the material. than

Hikers: do these socks work as a liner under another sock to help create a friction barrier?
