Just to answer my own original question for anyone else who is interested...we climbed Illiniza Norte on the 24th, good conditions, not much snow on top, a little mud, we wore waterproof low cut trail runners and were fine.
Climbed Cotopaxi yesterday (27th) in good conditions. Stayed at the hut from 4pm to midnight on the 26th, any other SPers there? Anyway, really nice refugio.
Glacier isn´t icy at all, lots of styrofoam snow, a few places where the powder is annoying for 50 meters or so, but that´s the worst of it. Snow bridges over the crevasses were fine, nothing steeper than 50 degrees, save for one 10 foot section of maybe 60 degrees. Nice climb in favorable conditions. Air was cold as the views were cool. Go figure.
