...and I'd like to say they made a world of difference, but, alas, no.
Unfortunately, I think I have pounded my feet to death the last month or so in those old shoes. I figure it may take at least that long for them to stop hurting with the new shoes. I also started some foot and ankle stretches last night. That's probably something I should have been doing a long time ago, too.
On the bright side, the new shoes didn't cause any new pain, so I figure that's a plus.
