Eh, well, you can probably guess my reply.
We very often have wet feet – it happens when you walk through rivers. But we never use anything on our feet. Loose shoes and thick wool socks seem to handle everything.
The whole ‘wet feet’ thing is a bit strange. Underneath a ‘dry’ layer of dead skin cells on the surface of your skin, everything is wet. You only have to scrape or cut your skin to see that. So all you are doing is keeping the very thin layer of dead skin cells dry – and of course they are not really dry anyhow. The wet layer underneath sees to that.
Some people worry about ‘trench foot’ and fungus and tinea and so on. In my experience, the cure for all of that is to wash your feet every day – thoroughly. We get the tent up, the packs inside and then its off to the creek (if there is one) for a wash. The upper part of the body might get a rather perfunctory wash if its cold – you try washing in melt water! But our feet go IN the water for a good wash. Kinda numb on the outside for a moment sometimes, but they feel pretty refreshed 5 minutes later.
It works for both of us, and that includes trips of 1 -2 months.
Cheers
