Does anyone have experience with the Zamberlan IBEX? What are your thoughts on them? I want a very stable boot for the higher rough elevations. My Hanwag Alaskan GTX that I have been using are great but I need more toe room so I am looking for something in the Zamberlan line up that is on par with my Hanwag Alaskan GTX. I am curious if The IBEX feel like insulated boots….I was told they have what would be equivalent to 200 grams or less insulation…I like un-insulated boots but am thinking at this level they will be OK. Any input would be appreciated.
