Avoiding or dealing with blisters

[mr.bond]

Hello all, i do quite a bit if running and have started getting blisters, even on long walks (3 hour+).
I've purchased running socks to assist but they don't seem to help. The blisters are always in the same place, to the side of both little toes and they hurt like hell.

How do you guys deal with, or even better prevent blisters?

Cheers all, what tape do you use?
