Thanks Nick, yes it does help a lot.Nick said:Hi Greg
The shoes will give you two completely different feels and rides, and the quick answer to your question is that the Adrenalibe will offer you more support. The Kayano is softer, smoother, lighter and for some people the perfect shoe. The amount of support is moderate. The Brooks shoe is definitely firmer and stiffer and subsequently offers more support. The Kayano is a joy to wear staright from the box, the Adrenaline needs a little running in, but is worth the wait.
Hope that helps.
