In reply to timmyhobby:
As they're not only for Elbrus the mentioned Scarpa Phantom 6000 or La Sportiva Spantiks are good. Both have new versions out now or within the next weeks. Phantoms should be a bit overkill for Ice Climbing, but still usable if you don't fancy having half a dozen pairs at home each for a different mountain
Remember... it's not only height. Denali is not 7000m, but I wouldn't even think about doing it without double boots. Vinson is below 5000m but the same applies. So above boot would generally be suitable for around 6000m depending on which mountain you're attacking, a bit warm for Scottish Winter or Alps maybe, but toes don't fall off when they're sweating, right
Edit: Also.... weather can be quite different on summit day. You may be lucky an have an unusually warm period, but it can be the other way around as well. So if someone climbed Elbrus in Meindl Borneos doesn't mean you can do it as well
