In reply to Stash: It's also recommended to remove any footbeds and check there are no bits of grit or small stones that could damage the goretex after using plus Superfeet have a bit on their web site saying they will not guarantee their product will not damage goretex liners, however in my case the boots were brand new and leaked and many reviews complain of new goretex boots leaking.
Scarpa are using a material called outdry which has some good reviews.
