Holy shit, why are people so concentrated on the price??
Make sure the boot FITS, so your wife will have a good time on the hill and won't complain. Boots are the single most important piece of equipment you have, considering it is the only piece that physically touches you.
Who cares if the boots are priced relatively high or low...MAKE SURE THEY FIT PROPERLY. That is the risk you take when buying online...are you willing to roll the dice?
Because she and the OP are looking for a deal.
But you're absolutely right - they need to fit her.
I ended up with mine because they were the only boots that fit my feet. It was a bonus they were past season and a deal. I was looking at a new Nike model way over what I wanted to spend, but was willing to spend it IF they fit well. They didn't.
Agreed - I personally would be very wary about buying boots online.
