Head"s Vector series is like the big brother to the Head Edge series. The Vector"s are bigger, and stronger, but still have a fantastic level of comfort that the Edge lineup is known for. These Vector 100 feature a 102mm last width and an adjustable flex rating that adjusts from 90 on the soft end to 100 on the stiff end. These boots are advanced, to be sure, as the fairly high flex and fancy features would indicate--but these are comfortable advanced boots. These are amazingly versatile, especially for the skier who spends half the time going fast and furious, and the other half of the time on bunny hills with the kids and fam.
