I think the Aqualung Express fins are a great choice for seasoned divers.
They don’t break the bank and are extremely sturdy so I can imagine these lasting many years. I was also really impressed with the grip on the underneath of the fins, it’s a lot stronger than other fins I have tested. Always handy to have that extra stability when on board the boat, especially in choppy conditions before entering and after exiting.
Do bare in mind that I have only tried the style with fin straps (known as the ADJ), not the full foot fin. After further searching online, it does appear that the full foot fins are more commonly available than the fins with straps. The spring straps are brilliant though – Aqualung never disappoint in this area – they are so easy to put on and remove, even with 5mm gloves on. If you can get your hands on the ADJ then you’re winning!
