StylinLP,

The Salomons I've fallen in love with and which seem to be quite durable are listed as "XA3D ultra2". I suspect they are pretty much the same shoe, but they are a couple of years old, and that your designation is simply the current one. They are made in VietNam.

Incidentally, many hikers (not me) like to use a replaceable insole in their shoes (replace when inside gets worn). I notice that the insole does not slip easily out of these, so if you are one of the users, you may want to take a pair with you when you buy the shoes to make sure they are large enough. There's a particular brand of such that is popular and mentioned on here from time to time, but I can't remember, and search function does not work for me. Maybe someone will chime in. It's a common way to extend shoe life on the trail.

best, jcp
