These fins have improved my times but l suffer more fatigue. With time and training this will be less of an issue.
The size is correct for me, XL, but it takes a while to fit as the top of the foot fitting is not as pliable as my other 'normal' fins. Will try some soap.
A happy purchase.

This fins are really good, my son likes it a lot. The only problem for us was that even if we ordered his regular size - they were too tight and he could not use it during competitions. So I had to order a second pair one size larger and it fit perfectly (3XL for EUR 46)

It took time to get it, and when received, it looked like a second hand, but it is expected as are hand made.
It was for my kid, and he, as a professional, is very happy.

Fast delivery. Nice to swim and really fast!

Buen producto y de calidad. Muy contento.

Good afternoon, the fins you provide are very excellent.
They allowed my son to improve his performances so as to be admitted to the Italian salvage championships.
Thank you very much.
Best regards

Fins pockets loosen up a bit after some use, so they are more comfortable, still hurt my feet after 1000 yards, Extra stiff blades are VERY stiff, - love the fins, but feet are not tough enough yet, will report back in another month - wac wac wac

Very stiff fin. Swim fast, but they hurt my feet. Great training fin, but a lot of fin to push. They hurt my feet, but I keep using them because they are so dam fast

We get this model for our lifesaving team each year. Great for training and competition. Fins are very well built and perform really good in the water.
