Greg Gavinwrote a review of Scarpa F1 Alpine Touring Boot on December 5, 2018
Familiarity: I've put it through the wringer
This is the second pair of the F1's I've owned. The first being the older teal color. These boots at the same last width, but have a stiffer liner, stiffer buckle strap, and power strap. I somehow cracked the tongue on my brand new boots on day 2 of the season. So either the plastic used on the tongue is different this year or I just had bad luck that day. In contact with Backcountry.com right now about a warranty.
