I'm a prettty light sleeper, so I think I'd notice if someone kicked me in the shins in the middle of the night. (My poor husband can barely exhale without me snapping at him to "stop snoring!" so it definitely wasn't him.)
My shins are achy and mysteriously black-and-blue.
I've only logged about 200 miles on my current shoes. Time to get a new pair, perhaps? I never heard of shins looking as bad as they felt due to shin splints, but running is full of new discoveries for me, some of them less thrilling than others.
