These things looks ace. The only problem is that my mountaineering boots (which look extremely similar) are kevlar, goretex, supersexyfabric, bombproof, bulletproof, crampon-proof, Alp-proof and indeed mud-proof and still cost less!
I can't speak for Haglöfs, obviously, but I'm guessing that the explanation for the price would include the high cost of the materials - light and tough stuff tends to be pricey - and manufacture and the inclusion of the mouldable SOLE footbed, which retails for around 30 quid on its own. Ultimately if they're perceived as overpriced, then they won't sell.
It must be the SuperFabric .. according to the hype this boot "takes on even the most inaccessible terrain effortlessly" and has a GoreTex lining "to guarantee optimum waterproofness and breathability". That's a lot of hype for the money!
I'm still very interested in the boots because they do exactly what I want. It's just a pity they cost so much!
Having thought about it a bit, however, most lightweight crampon-compatible boots are pricey (eg. Trango Evos). There are few fairly technical boots under about £180, and I can't think of any that are lightweight also. Boot prices have gone up a lot since I last bought some, and that was only 2008.
