Honestly I would give the these more like 2.5 stars, or 3 if the approach was short.
In a recent trip to the Tetons I took these up to, or above the Lower Saddle 3 times. If you're not familiar thats like 7 miles and 5500ft from the parking area.
The good: well constructed, water proof, sturdy, stiff soles, take light crampons well, climb well without any foot fatigue. The ascent, scrambles, and lower fifth class climbing felt very comfortable in this shoe.
The bad: the stiff sole allowed very little flexibility on the descent. I adjusted the laces many different times, to see if I could alleviate some to pain on the way down. The toes of the shoes are narrow, and facilitate climbing very well, but are very painful coming down.
This shoe is rugged and sturdy, almost like a low cut mountaineering boot. My wife climbed with me and wore Salewa Hike Trainer (mids I think?). The two shoes are very similar, and she had the same problem. In fact she carried an extra pair of trail runners just for the descent.
I ended up wrapping my toes in climbing tape to make it the last 3 miles to Lupine Meadows-- and I'm good at suffering.
I originally purchased this shoe for the Grand Traverse, but would not take them on that route due to the immense elevation gain and loss. I could probably recommend it on steep approaches, shorter than 2 or 3 miles. I will not take them on an alpine route again.
This shoe also runs large. I wear a 10 to 10.5 in everything, 44 in La Sportiva, and had to purchase a 9.5 in this shoe.
