My only GTX shoe is the Scarpa Ribelle Kalibra G. Worked wonders when I was crossing Cross Fell last January during a night time white out blizzard and was around -20c and with around 130km already in my feet.
Couple of years ago I did 100 miles in 24 hours in the HK July heat. There is no way on earth I would have been able to do it in GTX shoes and yes, my feet as well as every other part of me was soaked and was on dry trails or roads.
Anyway the OP can make his/her own mind up and at least the warning of the GTX shoe has been put out there.
