Depends on terrain kathoola spikes come off when used hard. Crampons too aggressive wood gets stuck in them and aluminum ones not good in the rocks. Calk boots work really well in the wet forest steep mountains getting up to where the goats are in coastal areas. But with a review like you gave you must have used them and they didn’t work for you. If the guide is recommending them you should listen to him.Calk boots seem super archaic to me for mountain use. I think loggers and tree aborists still wear them, but in the mountains? That’s not actually a thing that I am aware of. Is your guide a 130 years old?
Light duty, aluminum crampons (Camp makes a light pair) or micro spikes. Of the brands I’ve tried, Kathoola are preferred or the BD, but BD are lighter.
