Early Summer or Late Spring?

It was over 80 degrees this afternoon, but I didn't care. It's still nice enough to be part of Spring and I'm going to take advantage of it. This was also a 6-mile run on a weekday and it felt pretty good. My left knee still gives me a twinge at times. I'm thinking it's part of the transition from the old shoes to new and the corresponding adjustment. Today I wore the old shoes. Saturday I'm planning on wearing the new ones. I don't know - I've had issues with new shoes and how my kneecap tracks with previous switches. This time it's not horrible, just a few reminders here and there. I've also had this problem with new everyday dress shoes, but eventually it works out. Or not. As I've said before, more to come.
