Yes they do 'mushroom' out a bit in the toes but if you align them properly and pull only somewhat snug it all evens out. It has never been uncomfortable in my shoes. These will pull very high without much effort. I am 6' tall and I have to be careful not to stretch upward as I put them on or they would go past my knee. That's not a bad thing I guess. I just don't want them bunched up around my calf. At first I thought they may not be tight enough but after wearing a full day I can see that if they were any tighter it may get uncomfortable. Really, I think these are perfect and they do work. They are thin and breathe well. I will be buying another set.
