Brandonwrote a review of Dynafit ZZero 4 PX-TF Ski Boot - Women's on October 1, 2013
I bought these for my girlfriends birthday. The pearl plastic had discolored to a ugly yellow. I looked to Dynafit to replace and this was the response "That is not really a warranty issue since it does not affect durability of the product." Luckily Backcountry took these back and took care of shipping.
