Fins?

[freedivernd]

Tim, the ones you used were Cressi Gara's 2000hf fins. A good fin and also a fin with a good following. A bit stiff for some people, but can really generate the power.
I think the main reason for full foot fins is the claim of a more efficient transfer of power with a full foot, but I have also read contradicting articles to that from what I believe were reliable sources in the finswimming competition circles (more related to monofins).
To me, it seems that a full foot fin with a sock would be more streamlined than an open heal with a boot/sock or no boot/sock.
They do have open heel freediving fins available... some of the better models too. I've seen them on the deeperblue site under "Shop". You might check into the freediving fins at leisurepro too.
Fins for the budget... Sporasub H. Dessault fins probably get the vote there.. and they are available with open/full heel. Excellent foot pockets and removable blades if you want to upgrade in the future.
