I have to say normally for me at least, blisters are more of a nuisance.  Recently however, they really have been a pain.  In the past, all I have had is blisters on my pinkie toes and rarely on my heels.  But currently thanks to my new Blochs, I have two open blisters, on on each of my heels and two more on my right one.  One on my big toe and the other on my pinkie toe.  They are also lasting way longer than they usually do.  The ones on my heels are especially painful.  They started off as normal blisters and gradually got worse.  They are now pretty deep blisters that have bleed through my pointe shoes.  Which has not happened to me in a long time.  Like a really long time and they have never bleed as much as they did this time.  Ugh.  It's been pretty painful and has kept me up at night too.  Before and after class I have band-aids and Neosporin on my blisters.  Then in class I keep duct tape because nothing else prevents my heels from rubbing against my shoes and stays on.  Duct tape works but it is a bit hard and painful to get off.  I still do love my new pointe shoes, they have been working really well minus the blisters of course.  Anyways, as always have a great day and just keep dancing! ~Mia
