yo, no one noticed that ID AM1 have a little less crampons on outsole than General release (they are smaller and less high), in my opinion they will wear faster than the GR (I walk a lot it happens to me regularly have the outsole completely shaved), it also looks like the rubber is not the same (but for that I'm not sure, it seems harder on ID's)
if really needed i can take a picture to show the difference between a new ID outsole and a new GR outsole... it's not huge but we notice, not the same outsole
