I need to replace a pair of Salomon Super Mountain 9s (leather, moisture lining, big rand, takes step-ins, etc.).  Typical use will be snow/glacier/mixed slogs up volcanos and similar climbing.  Anybody have advice to offer about a good comparable replacement?  I have medium-volume feet, and the Salomons always blister me even though they are WAY past broken-in.  Thanks for any help. 
  
NEW-BUT-RELATED QUESTION:  Anybody have any experience with Raichle mountaineering boots, particularly the 90-Degree GTX?  Any advice on foot-volume considerations, comfort, break-in, flexibility, etc., would be most appreciated.
