I originally purchased these because they remained me of a pair I purchased while visiting my sister several years ago, Ukala, and Ive worn them even in the summer inside the house because Ive always been cold natured lol. BUT these are NOTHING like what I was expecting. Opening is narrow then more so towards the foot. Once my foot was inside, bottom part was comfortable but thats ALL that was. I actually thought I would have to ask for help out of the darn thing. Was so disappointed.

If this helps anyone my boot size is an 8.  140lbs and 58  Much better luck to yall out there
