I've just bought a pair of Cressi Pluma fins which seem to be ok. Definitely not as good as Ala's but I don't think there's much that is! The Pluma's are pretty comfortable (I don't wear socks or booties) but I don't know how long they'll last. At $69 I thought they were worth a go. I've only played about 6 games in them so I'll keep you posted with how they hold up.
