There great boots if they fit you well. They do have a high instep like most atomic boots, so hopefully you have a high arch/instep. If your foot is low you may well develop heel hold problems and pain in the shin. Try on the salomon Impact 120 as well. They fit vertually the same other then that the salomon is lower in the instep.
Only last thing, if you need more width in the forfoot, it can be hard to strech (not inposible just harder then most boots) that area because of the weird flex part of the boot.
