This is the dozenth endorsement of Altberg and the second or third for those Saloman boots so that gives me two starting places.
Recommendations are one thing, but you have to try them on and see if they suit you. Try on lots of boots and see how they feel.
The great thing about some of the Altberg boots is half sizes plus the 5 width options. If I remember the widths are extra narrow, narrow, normal, wide and extra wide. I take a wide.
Bear in mind also that a boot like a Salomon Quest 4D won’t last anything like as long as your Scarpa SL’s. Leather is tougher and also the stiffer the boot generally the longer it will last.
