Glad you're liking them. Honestly, I do wish they'd return to the WR 13 design. It remains my favorite. I have a couple of them that have been relegated to gym (but not running) workouts. They were a bit lighter IMO. But still, I think it's a good shoe for those of us with narrow heels/feet. Very little else works for me, although I've yet to try any of the minimalist shoes.
