Jeff Mikaelianwrote a review of La Sportiva Core High GTX Boot - Men's on August 2, 2017
Familiarity: I've put it through the wringer
Fit: True to size
Great lightweight hiker. I did have trouble sizing. They do have a fairly wide toe box as I was told. I sized up .5 size as i usually do with LaSportiva, but it was too big. So try on if you can.
Traction, Their sticky rubber and Impact Brake system do work. in my running hoes and the core, i think they are great. Sure you can slip on many things in various situations, but these grip better then most.
