What are your opinions on the brooks adrenaline gts 17? I have been training in the saucony kinarva model since the 5th addition on up to the 7. Anyone run in both and how was the transition? I have a friend who loves them and I tried them on and they felt great but I heard they feel pretty clunky as the run goes on.
The Adrenaline is a stability shoe and the kinvara is a neutral shoe. The former is recommended if you pronate, the latter if you don't. If you want a brooks neutral shoe try the Ghost, or the Launch.
I found them to be a bit rigid, like they needed to be broken in. They were fine underfoot and responsive enough for that kind of shoe but the upper did not suit me. Used to a plusher feel around my foot.
I wear them for non running stuff.
One of their tech reps brought the 18 out to one of our club's track workouts and it looks like a much better shoe. Clean upper and not as stiff. She said it comes out this fall.
Those two models are about as different as two running shoes can possibly be.
Kinvara: lightweight (7.8 oz), neutral uptempo trainer with low heel-toe drop (4 mm). Adrenaline: regular-size (9.1 oz) support trainer with extra-high heel-toe drop (12 mm).
You might enjoy running in both - Adrenaline for everyday use, Kinvaras for interval workouts or tempo runs - but if you liked the Kinvara as a daily trainer, there's no reason to switch to the Adrenaline now. They're both good shoes, but why would you want to switch unless you're having some kind of problem running in Kinvaras?
