[pct-l] Foot care question and how many days between resupply?

[Steven dvsteven]

Good morning all,
 
Does anyone use any type of foot powder when hiking?  Does it seem to gunk up in socks (unless of course you wash yours everyday or carry enough between resupplies)?
 
Also how many days do you plan to average (or did you average) between resupplies?  I'm planning on between 8 and 12 days on my upcoming thru.
 
Thanks,
