So I went on a dayhike the other day and ended up with severe maceration, and was wondering what causes this and how I can avoid it in the future.
In the past, I've never had it when I was wearing a coolmax Injini liner toe sock covered with a medium weight wool sock from Smartwool. (I also wear trail runners that drain well.) I've hiked in much wetter conditions than I experienced this time and never had a problem. The time that I got the maceration I was wearing the liner socks with a very, very thin wool sock over them. I'm wondering if that could have contributed to the problem? Also, these are different trail runners than I'm used to (New Balance, rather than my old Adidas supernovas), so it's possible that the sole of these shoes retains water more? It's strange because it was a medium-hot day and I only crossed one stream a few times back and forth, so there was only one period where I got my feet wet. It didn't rain all day. Any help appreciated…?Apr 25, 2010 at 8:34 pm #1602025
Hydropel worked pretty well for me on the Lost Coast hike. My feet were wet pretty much the entire time.Apr 25, 2010 at 11:00 pm #1602072

Maceration is not a term that I'm very familiar with. So I googled it, and didn't find much helpful info. Can you describe it? What I've learned is that it presents as peeling skin, perhaps commonly caused by repeated wet/dry cycles, like sweaty feet that dry out, then sweat again. Is it just peeling all over your feet? What's it look like?Apr 25, 2010 at 11:43 pm #1602078
If you go and watch, "Platoon" you'll see Junior get in trouble for spraying skeeter repellent on his feet to simulate maceration.
Maceration, in terms of what you might find on the bottom of your soaked feet, is when they've been wet for so long (shrivelled, whitish and puffy) that the skin begins losing its protective properties.Apr 25, 2010 at 11:51 pm #1602079

Sounds like Non Freezing Cold Injury (aka Trench Foot)?Apr 26, 2010 at 12:36 am #1602085
Maceration could be an aspect of Trench Foot.
For example, nausea, fever, or physical aches could be an aspect of a flu, food poisoning, or an impending visit from in-laws.Apr 26, 2010 at 12:44 am #1602086
Maceration occurs before trench foot. It is the condition of having the skin on the feet fold up or wrinkle so much that it's painful to walk on. If not healed, the skin can get infected (fungal usually) leading to trench foot. That's my understanding of it. This was just a dayhike so didn't happen, obviously, but thought it strange considering how I got it on a warm, dry day and a 7 mile hike.Apr 26, 2010 at 6:44 am #1602115
Maceration- sign/symptom of skin breakdown from prolonged wet feet plus friction. (may be other causes)
Trench foot- cold injury from cold and wet feet.
You should avoid prolonged soaking wet feet.
1. Let feet dry out at least once during the day (and also overnight) if they are soaked from water crossings.
2. Try skin application like hydropel.
3. Sock combination could be a variable if they do not dry out easily.
4. Shoes that drain well.Apr 26, 2010 at 7:53 am #1602147
I think this is where lightweight shoes that drain quickly and wearing very thin (if any) socks help. I've seen this in the past, and it was typically with people wearing leather or goretex boots/shoes that didn't dry fast once soaked from inside.Apr 26, 2010 at 1:52 pm #1602316

I have some new balance cheap sneakers that hold in a ton more water than other shoes that appear to be made of similar stuff, so I suppose that it's possible your shoes contributed. I mean, my shoes drain quickly but the fabric itself doesn't dry very quickly. Other shoes I have drain just as quickly but the fabric dries much quicker.Apr 26, 2010 at 2:00 pm #1602318
I'm gonna give em one more shot, this week, and if it happens again, I'm going back to the Adidas. A shame because these New Balance have much better traction.Apr 26, 2010 at 2:18 pm #1602330
Wow, I wonder what else could have led to it? I just finished around 23-24 miles, lots of steep, prolonged ups and downs (Black Forest Trail in PA), rainy, cool 50s all day, and my feet were never dry after about the first mile (I was either wading in water (repeatedly) or getting my feet wet from the soaked vegetation, they simply never had a chance to dry). Wearing NB MT100s and a pair of Icebreaker ex. light hikers only. My feet weren't even really shrivelled at the end of the day, certainly not painful. Could there have been some fungal problem from something?Apr 26, 2010 at 2:59 pm #1602362
Well, maybe it was my change of socks?
I changed two factors: sock setup and shoes. So no way to know which was the cause, but I'm going wading in a river for a mile this weekend and will use my old sock set up.
There wasn't any fungal problem. I got home, aired my feet out, and they returned to normal the next day. As far as I understand it, this is what happens: wet feet leads to maceration, which makes skin crack and makes it *more prone* to fungal or bacterial infection. Fungal being more common because it grows in moist areas of skin. So the maceration isn't caused by fungus. They are both caused by water. It wasn't cold at all the day I hiked. It was warm. Very strange, as I've hiked in all day wet weather, colder than this, many times with no problems whatsoever.Apr 27, 2010 at 10:36 am #1602768
