Jonathan Whitewrote a review of La Sportiva Boulder X Mid GTX Approach Shoe - Men's on July 20, 2016
Familiarity: I've put it through the wringer
Fit: True to size
In general I prefer high top shoes over boots to hike in. I have several pairs of La Sportiva boots and rock shoes so I figured I would give these a try.
I wore these for a multiday climb in the Cirque of the Towers. I varied my socks between liner and light hiking sock, liner only, and hiking sock. Regardless of combination my feet were super hot and sweaty-- temps were in the 50s and 60s.
Super grippy, climb really well (better than my low top 5.10 guides)
These shoes are hot and don't breath at all. My feet were miserable for most of the time they were in them.
