For wet weather walking, there are a number of thing that I will do and not do. Here are a few that may add to what you are already doing.
- Apply a good layer of goop (there are a number of choices) to your feet to keep a barrier between skin and water. This will help control feet from becoming macerated and more prone to skin damage, including blistering.
- Wear thin, light-cushioned merino wool socks. Thinner padding will not absorb as much water as thicker socks. Merino wool will also keep wet feet warm and comfortable in most seasons and temperature ranges, unless the weather is frigid winter-cold.
- While I prefer merino wool socks, there are some decent synthetic-blend socks, specifically designed for hiking, which can also work well.
- During rest stops which will last longer than 20 minutes, take off shoes and socks to let feet air dry. During that time, I will wring out any excess moisture from the socks, but I will not put on either of my dry pairs (I take three). Putting on a dry pair will mean you will have two pairs of wet socks to deal with. I dry off moisture on my feet and then reapply a goodly amount of goop to my feet to help keep them from becoming macerated.
- Carry an extra pair of insoles. I do not carry other footwear, but I always carry an extra set of insoles. These extra insoles do not have to be the same as the expensive “walking” insoles that you purchased separately. I use the same lightweight pair of insoles that came with the shoes. These will be the barrier between your wet footwear and your dry socks when you are done for the day and if your shoes are a bit damp come morning.
- I find that at days end, I can remove the wet insoles and use absorbent paper or toweling to sop up as much moisture as is possible while I am showering and dealing with end of the day chores. When I get ready to go to dinner or to wander around town, I insert the extra pair of dry insoles into my shoes, put on a pair of dry Merino wool socks, and put my shoes back on. This accelerates drying out the shoes. Depending on the shoe’s material, within a couple of hours the shoes are mostly dry.
- At bedtime, I remove the insoles and stuff absorbent material into the shoes to continue the drying out process during the night. Most of the time the stuffing is not needed, but if the shoes are still a bit damp they will finish drying by morning.
**** I usually make my own 'Goops' from a mixture of lanolin and beeswax that I gently melt and mix together, putting them into my own containers. However, you can find ready made products that have incorporate lanolin and beeswax as a primary ingredient. Examples: HikeGoo, Gurney Goo
Personally, I do not like vaseline/petroleum jelly stuff -- unless mixed with a good percentage of lanolin and/or beeswax -- because it tends to absorb into the skin and wipe away far too quickly. Petroleum jellies are just not persistent enough by themselves.
2Toms is a dimethicone-based product (siliconized polymers) which does work for wet weather walking. I started using it as an anti-friction, blister prevention (it rolls on). During rainy and wet days I experimented by first applying and letting dry the 2Toms product then also applying Goop. I liked that combination.
There is now an enhanced and fortified version 2Toms calls 'Chafe Defender' which is claimed to be 'military grade'. I have not used that version, but if I ever buy 2Toms again, I would chose that variant.
