I got these for winter trail running and summer day hiking, climbing Mt. Monadnock and a few of the easier Whites. The Gore-Tex is great--my feet are always dry. As for size, these shoes were narrow for me, and I have average width feet. Sizing is weird..the shoe is longer than it should be; they took a while to break in. I also used blue superfeet in place of the thin and unsupportive Salomon insole. On a dirt and root trail, these do very well. You can get away with hiking in them (it's not their stated purpose)--but they don't grip well on granite, wet or dry (I have bruises to prove it), and the small tread lugs wear away pretty fast if used on harder surfaces like pavement or rock. After a year of use, my Salomons have little tread left and are good mostly for mowing the lawn in. Because of fit, high price, and tread issues, I would not buy them again.
