To preface; I am new to alpine mountaineering, only experience is numerous non-technical Colorado 14ers, both winter and summer summit. That said, my first high ascent will be a guided climb of Pisco in Peru, at 5700 m. The climb will be in late May of this year.
The summit push will be from moraine camp at ~4950m. From what I understand, the approach to moraine camp should be doable in approach shoes.
BOOTS:
The boots I have for my wife and I are, La Sporteva Nepal Evo GTX, and Salewa Pro Guide ( I also can get Pro Vertical), respectively. The Peruvian guide recommended double boot, but pragmatic local friends suggested that a single boot would be adequate, given the summit bid begins from moraine.
The price jump from single to double is substantial, so if I can get away with my current boot that would be ideal. I also want to be able to use these boots at home for all my winter shenanigans.
If you really think I need double, what is a good variety? Any thoughts on the Baruntse vs Spantik?
