Choose how you want to rotate
Decide how many walking days you are willing to use a pair before a wash. That is your planning assumption, not an odor or hygiene guarantee from this guide. Enter it explicitly instead of using an inferred rule based on fiber content.
Mark real wash opportunities
Identify the days when washing is practical in your own route plan. The planner applies those events at the end of the selected day. It does not assume a wash is available every time a pair has reached your chosen wear limit.
Allow the drying time to finish
Enter the hours you expect a washed pair to need. The planner only returns it to the rotation after that time has passed. Try a slower-drying scenario to see whether the same carried count still works.
Protect a reserve in the arithmetic
If you want a separate dry or sleeping pair, reserve it. The planner excludes reserved pairs from walking stock. A shortfall cannot be solved by silently consuming the pair you meant to keep separate.
Check a system as separate pieces
If you plan to change liners more often than outers, run a separate plan for each component. Give each its own carried count, wear limit and drying assumption. A complete sock set can contain materials with different care instructions.
For early rubbing, shifting fabric or a damp change, follow the hot-spot prevention guide before continuing your sock fit experiment.
