In reply to PPP:
Hmm, I got my first pair of GT-1000-GTX simply because I found a pair cheaper than the normal GT-1000s that I was looking for (think I'm on my 4th or 5th of the various GT-1000 iterations). Just found they were that bit better, always kept my feet dry when it was wet.
A couple of things that you mention don't apply to me and they might be where the GTXs don't shine:
- Biblical weather - that's me still inside then 😁 unless really caught out on the run, so I've not experienced the feet wet even with GTX (when of course they'll take longer to dry out).
- I only run up to about 10k and that rarely, usually in the 4-8k range. So that probably means my feet are less likely to overheat with goretex.
Always the outsoles that go first for me.
Funnily enough, when orienteering I use Mudclaw 300s and (of course) then I don't give a damn about wet feet. The only thing I want is for each orienteering event to have a convenient stream near the finish so I can easily clean all the mud off.
