I'm a ghost lover and didn't realize these were the Gortex ones. Ive ran in these for about 3-4months, anyway from 5-20mile weeks and have really liked them. I've ran in the rain and the inside of my shoes haven't gotten wet yet (and it's been fall so rainy and snowy)...I've been thoroughly surprised and never thought the Gortex was worth it but now may have to reconsider.
