text: I have worn the previous Brooks Adrenalines 13 & 14 & LOVED them. Bought the 15 & YUCK! They fit differently & are no longer cushy. They run a half size shorter, so if you want to stay with the adrenaline you will need to order a 1/2 size up. I was told they have redesigned the insole to be denser & it feels hard as a rock! I took them back & have now switched over to the Asics gel nimbus 16. Why oh why, Brooks, do you have to mess with an awesome shoe??? :-( so disappointed!
