You will find a lot of recommendations to buy boots that are too large. When you do, your foot will slide around. Sliding is friction. Friction is blisters.

It all will start with properly fittings boots, though, so stop buying the ones that are too large!!
Falcon,
you are right, just buying boots an extra half or full size larger is a bit pointless. My advice is to plan to make the purchase along the following lines:
First, choose a store that has a proper testing ramp - a platform that has a slope that allows you to see that the shoe/boot clears your large toe when you are pushing down into the boot.
Second, plan to get the boot fitted late in the day, and walk as much as possible during the day, including parking well away from the store so that you have a final walk.
Third, take along the thickest pair of socks they you might use, as well as any orthotics etc that you know you will use.
Finally, take time to walk around, use the testing ramp, jump up and down, get the staff to find you a weighted pack back and try walking with that on as well.
Even then, see if the boots can be exchanged if they are not the right size. Consumer laws will differ, but most firms here in Australia will allow an exchange if the boots haven't been worn outside. If my three steps have been followed, it is less likely that the size will be wrong, but it is still possible.
