This question reffers to "single" alpine climbing boots used for mountaineering with a stiff 3/4 to full shank, not heavy duty backpacking boots or "double" (plastic) boots. I have owned two pairs of climbing boots, both of which have caused foot pain and/or blisters on many trips. While climbing 3rd to 5th class rock or climbing vertical ice/snow, I appriciate the stiff shank and am able to stand in my crampons and climb in boots just fine with no pain. However, most of the climbing in my area requires long and sometimes bushy approaches on anything from level ground to steep hills. I find my feet start to really hurt on the approach (even more so on the walks back to the car) as the boots are so stiff and hard on my feet they seem to really pound with each step.
I guess I'd like to know, as the boots are designed for climbing, should I always just expect this when walking on flat/moderate terrain?
