I am posting this because I and some of my friends had enough with Imersion fins where it is getting cracked in a very short time the fins are the Black and Blue fins which are made for freediving... Please if anyone using those fins and having the same problem mention it here or i am not sure if they are only ones which are in UAE having this problem. The last incident was happend with my friend who used the Black type for 4 or 5 dives only before it crack... The blue fin had one crack incident but it can be normal because of use but the black fin will break in a very short time...
