In reply to Rhys Jones: I've not used any of the newer Scarpa boots yet, but have used the older 6000's and the Spantiks.
I can safely say that the Spantik is my favorite boot of all time. They do tend to be a little more expensive than its competition but thats because they are simply better.
There very warm and should be more than warm enough for upto 7000m. Just remember to take a spare pair of the laces as they tend to snap every now and then. This shouldn't put you off though, their lace system works very well.
Compared with the Phantom 6000, I feel that they were warmer and definitely lighter, plus they look much better which has to be an advantage.
I don't think you can go wrong with Spatniks, but as with all boots you need to try them on properly. If they don't fit your fit then look at another model.
