this is what happens when you run an 8km race with slightly wet feet sans sox. let me tell you exactly what you're seeing. the top half of the blister healed nicely, has a couple of flecks of sand in it from the beach but is painless. the angry red part of my foot is from where my sandals *further* aggravated an already annoying and painful problem. i also had a couple of slivers in that part so had to take a pin to it and painfully dig them out. gross, eh? moral of the story is, if you hear your feet squeaking, fix it. oh, and word to the wise: salt water feels really really bad on fresh blisters.
