I can deal with the fit with a sock if need be. My main requirements is a rugged fin that performs adequately and wont break anytime soon as they'll be bounced off rocks regularly.
I'm under the impression that the Milleniums (black/green) are pretty solid in that department.

The Sporasub instinct polys are Sporasubs newest fins so there isn't much being said about those yet, They are guaranteed comfortable tho.
