traveling with these fins in the world's oceans. Okay, for the country's they are not really suitable, but that you should know when buying usually yes. In my mind and in my experience, very good for snorkeling. They give good propulsion and it never appeared the feeling with these fins are not positioned correctly or dissolve same by foot. Man kan really full on the underwater natural focus (or whatever ...). Also jumping into the water from the edge of a boat, etc. is not a problem if you dive with the first hoeing. Also during re-entry into the boat or catamaran can take the fins comfortably with one hand from the foot. Even with a Unterwassercam, I had no problems when boarding - a breeze.

From my side a full five-star rating or recommendation.
