User Review: La Sportiva K3

The K3's were the end result of my exhaustive serch for a boot that not only climbed ice/mixed terrain well but was comfortable for the often long slogs required for backcounty climbing. I usually eshew high tech mumble jumbo but I must confess that the carbon fiber midsole lends the boot the best blend of stiffness required for crampons with enough flex to be comfortable for extended hikes of any boot I've worn.

I am now in my third season with the K3 and can testify that it wears very well. Regular waterproofing (twice a season) has kept all but the wettest spring climbs on the outside. The thinsulate lining aids in warmth but I have found that below 10 F I need full gators to keep my toes comfy. I will definately purchase another pair when these wear out. Let's hope Sportiva doesn't change the line by then.
