As someone who has done an ultra or two, I can assure the dear readers, that the pics are very tame!
I'd suggest pre-taping areas as a matter of course. Ball of foot, back of heel and under heel, possibly big and little toe. KT tape (kinesiology tape), is your friend. Watch some vids, its an easy skill to master. Round off the corners of the tape. Put talc on the tape, before you put your socks on. It stops the tape from sticking to your sock and coming off.
1000 mile double layer socks or Injinji toes socks are good. Though the Injinji's are an arse to put on if you have any sort of plaster on your toes.
Waterproof socks are great. They often keep the water out. More importantly, they keep out the mud and grit, that act as an abrasive. When they do leak, you have a nice warm wetsuit effect, which is good in the winter. Your feet sweat, so even if they dont leak, you still end up with prune feet. You can get waterproof talc, from 2Toms. You put it into your waterproof socks to reduce the friction between them and your inner sock.
Edit: Try different brands of waterproof socks. Some are thicker/thinner/ longer/ feel or work better than others.
You can get low friction patches (Engo patches), you stick on the insole or inside of your shoes. If you always get blisters in one area, these are helpful to reduce the sheer and friction.
For multi-day ultras, some combination of all the above and luck seems to be the choice. You will always get someone who can do hundreds of km, non-stop, without a single blister. Which is just showing off really.
If you want to know more, the book Fixing your Feet, is considered the bible for runners.
