I have no problem with the idea of comfort, but it is not an important thing aesthetically. If you look at a shoe and immediately say it looks very comfortable, in terms of design, it is not going to excite me. Of course, I am not putting nails in my shoes to ensure everybody is in pain, but a heel is not a pair of slippers and never will be.
When I'm drawing, I'm drawing with the light, being completely open and creative. I can't draw in the evening. I need light and I need warmth if it is a summer thing, and I need cold if it is a winter collection. The good thing is that I have houses to go to whenever I'm working. I draw according to the place.
