These are very comfortable out of the box. I love UGG boots but these are even more comfortable than my boots. Soft and bendable, not heavy, wide enough toe box for my fat toes, good grip on soul. After months of daily wear the only spots showing wear are inside where fur is flattened and/or off in a couple small spots. I'm elderly so comfort and safety are my top priorities; these work for both. Fabulous find.
