here's what i know about nordicas:
they are generally wide boots (i fit in dalbellos perfectly which are skinny)
they have a bunch of different boots ranging from cheap to expensive, low to high flex... you will be able to find one for you (assuming they fit)
they are really comfy. when i went to the bootfitter last time, i tried them on just for kicks and i actually really liked them (for the fabric, kind of fuzzy on the inside)...
but, go to a bootfitter and they'll hook it up
