It was a good day...

I regret to report that I had to return my Trigon 4 Guides today. They lack the arch support I need. I ran in my Brooks Adrenaline GTS 5s today and felt great (4.3 miles; 41:28). I didn't experience any of the aches and pains in my knees that I did on Monday. This is my go-to shoe (Dan, you were right to question my decision to go with the Trigons over the 6s). I'd like to add another pair but probably won't find one. I plan to purchase the GTS 6s. From what I've read, heel to toe transition is smoother and the last curves in a bit more than those of the 5s. However, stability doesn't suffer. Great!
