It looks like Etnies have upgraded their new shoes with this STI Evolution foam which looks like it increases flexibility along with helping to resist heel bruising and more. Find out a little bit about the shoes from Ryan Sheckler (I know, I know… It’s not BMX) the hit this LINK to find out more! There’s even a little Chase Hawk quote in there.
In an unrelated part of this new STI Evolution foam, I came across a sneak peek of Chase DeHart’s signature shoe on the Cult website. Sounds like it’ll be out the 2nd week in June and doesn’t appear to be using the same system above, but should be real good for BMX. This is the Fader model if you want to do some research.
