I mean, I run 6 days a week so my running socks get beat up pretty bad. When they are dead, I need to throw them out. So my options are:<p>1) Buy 1 new pack of socks, throw out 6 old socks - repeat every month. Doing it this way I have to match socks between several different styles.<p>or<p>2) Put 4 packs of socks, throw out all of my socks, repeat 4x less often. Also I have no matching to do, as all of my socks are the same - just grab 2.<p>(And technically I have 2 styles of socks, summer socks and winter socks. Summer socks is a buttload of cotton socks that get bought in bulk. Winter socks are 3-4 pairs of identical wool socks that last much longer).
