@comidapicante Might be difficult getting nano 6.0s now as reebok have discontinued them with the 7.0 now released.
I haven't heard of the Asics though Joel in AMRAP seems to like them a lot.
I plugged this elsewhere but check out Nobull for a good all-round shoe.
In the end, depends on what feels comfortable for you. There is a great pair of stores in London (and a few other places now) that have a barbell, rope, and box to try some movements on with the shoes before you buy. See if there is a place like that near you.
@comidapicante you probably won't ever find Nobulls under $100. They create their own huge demand by producing very few of them, so they rarely have to do any sort of markdown on them.
