At this stage of the algorithm, we've reached a critical mass of justification socks.
Repeat steps 1-3 until all socks are sorted.
This step is crucial for minimizing sock loss.
For every 10 pairs of socks, one sock must be retired.
Place retired socks in a special bin for later disposal.
For every 5 pairs of socks, 1 new sock may be purchased.
Purchase new sock and place it in the designated area.
