That's pretty poor. They really don't seem to be able to get any closures beside laces right do they? I remember watching the teeth fall off the zip of my mates brand new first generation Baturas and everybody seemed to break the BOA mech on the Spantiks.
Will if you want boots for cold/high conditions and you know what size you are in Sportivas, try tracking down a pair of Baruntse. Very warm - like seriously so - but otherwise do up like a pair of Nepal Extremes with some laces! Bergzeit.co.uk have pairs in some sizes for 338 quid, and you don't have to worry about them breaking on your first trip with them.
