Yes, this is actually a common problem, usually referred to as a "pinch". it can be quite troublesome. There are several strategies: make sure you have a relatively wide shoe/boot, as pressure makes it worse.
liberal application of vaseline, to make the various parts slide easily upon each other sometimes helps a lot, but must be re-applied every 5 miles or so.
Applying a tape that allows sliding, like duct tape sometimes works.
Using a spacer of lamb's wool, with tape around the two toes to maintain the unit, sometimes works.
There is a tube made of foam, designed to slip over one or both toes, to maintain space. This can be found at most pharmacies.
Believe it or not, yours is a mild case. I've seen cases where the person consistantly got a blister on the tip of the little toe on any walk over a mile or two.
A visit to a podiatrist might also be in order
