New shoes

So it was new shoes time again, nothing spectacular just the same style of Kayano's I've had for a while. Also as usual they suck to break in. The first 2-4 runs are great, lots of cushion, still stiff so they fit well, and then it goes downhill for the next 10-12 as the shoes break in. Today was shin splints, yesterday was stiffness around the ankle...either way its continuous compensation for a week or so and throws me off my pace entirely.

Anyone have advice? I'm stumped as always but it drives me batty.
