The old ones had about 390 sweaty summer miles on them. There was not much support in the heels any more too. They were soaked after yesterday’s 7 mile class run on Town Lake (I timed the middle miles as I ran with Tom: 8:48, 8:27, 8:34, and was happy to see that I was back in the eights and not dying). So it’s time to unpack the new shoes, another set of Nike Structure Triax, I bought a week or so ago. And time to start counting miles on the new pair.
