I've channeling funds wg. bought the low weight, since one must take the plane only 20 kg. It was really worth it! I am so snorkeled two weeks in Egypt. They are very light, with them you can be very good snorkeling and without great effort. They float on the water. This is important when putting in water, they do not go directly below. I have shoe size 40, but I bought the fins in 38/39. When tightening on the Dry they were then also very tight, but in the water I could put them on very well u. So great snorkeling without them slipping. You are stuck, but are comfortable. That was a very good decision to buy!
