ok, i have cressi gara 2000 hf fins. i like the fins very much, but the foot pockets are not wide enough for my feet. every time i dive after about a hour or so of diving i get cramps in my feet. i need a new pair of fins. i would like to move up to a fiber/ composite fin. i need a fin with a wide foot pocket. i heard that the sporasub foot pocket is very wide. does anybody have and expirience with the sporasub grafiber fins? are there any other brands i should consider when looking for a new set of fins. once again i need fins with a wide foot pocket.
