We day tripped it from the TH just beyond Altzomoni and had no problems. It took around 9 hours I think with an 8:30 start. We wound up camping behind a building at the TH because of a miscommunication concerning the hut. If one does carry water to the higher huts, it wouldn't be that big of a deal as it is a relatively cruiser trail up to them. A couple steeper sections right before the minor passes, but not too bad.
Also, trail runners and bread bags would have been perfectly fine and far more appropriate for Ixta with the conditions we had a few weeks ago (Thanksgiving day in US). We seriously regretted hauling mountaineering boots and kit, but your conditions might be different of course.The Ayaloco routes are in pitiful conditions.
