Ok begin takes for spearfishing.
Bought my first flippers of this type, designed for spearfishing. Had no experience at all, so went for something cheap, which was not the most expensive, and something good. Have now been in the water twice, and they work ok. The first trip I had some problems with that I felt Finns just lay on the surface, so that half of my movement "kicked" was over. It must be said that I no Ankle has, as part recommend to uvjagt as I, so far, has downsized to keep the price down for a start. On my second trip I was, however, already a lot more aware of my movements in the water, and although I have not had here Ankle, so they seemed somewhat better. The water was calmer on another trip, maybe it has something to say. About the problem defeated completely by using Ankle I do not know, but I imagined myself. Thinking, however, one gets a little tired in the ankles ... In relation to the size. I bought with these fins a few Cressi 3mm neoprene socks. I usually str. 44/45 all questioning of shoes and brand. I bought these fins in size. 45/47, and they're really fine with neoprensokkerne on too. Highly recommended.
