Finally found a pair of the ADV Boosts on sale.

Freakin cool shoe. Very lightweight, fits the foot like a glove and is quite flexible. Feels very high tech on the foot.
I felt that there was little to no break in time required. Skated good right out of the box.
Cushion is what this shoe is about apparently, with the fancy-schmancy boost foam. I mean, what can I say? Its comfy as fuck and feels kinda bouncier than a normal shoe, but that could just be my imagination.
I typically skate vulc shoes, so the grip is taking some getting used to, but it should be ok.
The only downside is that the suede on the toe feels very thin and might blow out easily.
So to summarize:
Pros: light, comfortable and responsive. Looks like something a future man would wear.
Cons: Might explode if exposed to kickflips.
Overall, neat.
I'd get them on sale though.
