I have the Solomon GTX's, coincidentally so does
JayW as I found out.
Light, good support, especially with my custom orthotics.
My feet don't sweat that much. However, I always carry an extra pair of socks.
I'm wearing Darn Tough socks these days. I've come to like that tight weave they use.
So, at the risk of making your pack 4oz heavier
I would suggest you change socks, maybe several times while you hike.
Check your feet for potential hot spots. If you find one, cover it right then.
Hang the wet ones on your pack. They'll dry quickly...unless it's raining
There's nothing like the feeling of putting on
dry socks on a long hike.
Dry socks are a psychological boost if nothing else.
And do not
over train these last 10 days or so.
Take it easy on your feet and knees. Sounds like you are ok in terms of your heart/lung fitness.
Take care of the blister you have now. If you do walk some, consider covering it with mole skin.
The absolute LAST thing you want is to arrive here with a blister of any sort.
And yeah, I go with comfort over waterproof for hiking here in GNP.
Personally, I don't put much store in the "waterproofness" claims any of these brands make anyway.
If you get caught out in a rain storm, having those spare dry sox will be nice.
Gaiters can help keep your boots dry too, both from rain, and wet morning vegetation on some trails.
Get
short, waterproof, or repellant gaiters.
And don't tuck your long pants(if worn) into your gaiters. Some people think that looks cool...whatever
If you tuck pants
inside your gaiters , they'll work well to funnel water inside the gaiters and down into and/or on to your boots
Face it.
This first trip here will be a learning experience for you.
There's sometimes no way to know about some stuff until you just get out there and see what works.
"Just Do It"
