Which Roclites have you got? The 315 (?orange and grey ones) do have more cushioning in them than the lighter variants. However, cushioning is an illusory friend at best (and an ankle brutus at worst) - I think it's the lowest item on the characteristics priority list; (blister free> foot support/imobilisation > Grip rock > Grip wet grass > foot protection > cushioning ~ water drainage)

I wouldn't do it in a new shoe unless it was a new shoe of a type i'd used before... Mark's point about new shoes feeling a lot more cushiony is good. I think, as spooney attests, that Roclites are a really good choice of sole for the BG if not worn down too much. You do need grip at times on the descents - but you never need 'racing' grip - and the broad flat studs are great on the rock (there is a lot of rock) and the rubber seems to have a good level of stickiness.
