My first upgrade from plastic. I'm 5'7 150lb's and i got the soft version. Im fairly fit as i run a lot and surface swimming is still a little strenuous on my ankles. Having said that though, once you go under they're awesome. The power transfer is excellent. Ive only taken them to about 45' so far but they did it with ease. If you want it and put your back into it there is power in spades. Also the foot pocket on the current model is great. Hard on the bottom, firm over the top of the foot and soft near the toes and heel. I wear fin savers and these help keep everything snug. I'm a US 9, Euro 42 normally and the 7-8, 41-42 fit great with a 3mm sock. My feet are medium wide (10cm across when standing) and 25.5 cm long when standing against a wall. Great value far as i can tell!

Excellent product and service.

I have been using the Leader pure carbon fins for a few years now, they have been great and terrific value for money. My colleagues also use the same fins.
I pegged it back a star because the foot pockets could be better.
I'm in Australia and the fins i have ordered arrived remarkably within the week.
Great service response.

More comfortable and easier on the legs and feet than the cressi garra plastic blade fins I had been using.
I tested them in a 50 meter pool. It took the same number of kick cycles to go the 50 meters as the plastic fins. However felt easier on the legs and feet.
I'm happy with my purchase

I bought my first Pure Carbon Leaderfins to do spearfishing in Centro America. Those fins are the best that I have ever had. They are soft, very comfortable, fast, and the price is reasonable . I love them.

Excellent fin for the money. Fast delivery.

Love these fins! Amazing quality and great price! I am able to move and propel so effectively. Very fast delivery and packaged so neatly in a case.

Bought these fins for my son, for freediving, he loved them and so did everyone else that saw them. Very comfortable and adequate for freediving

I think this pure carbon fins are the best I've experience. I strongly recommend this fins if you consider buying this.
