Let me toss this into the lion pit:
It seems to rain a fair amount during traditional CT thru hike season, often daily. Suppose I am wearing waterproof shoes with rain pants during the watery times so that water does not drip down my legs into the shoe but rather onto and off, since they are WP. I know, I know...there is always some slop room for water to get in, but for the sake of argument let's say my feet stay rather dry this way. Are dry feet in the rain valuable enough to offset hot feet (well, hotter in WPs than non-WPs) in the dry times?
