What is the difference between stiffness 1 and 2

The stiffnes 2 is 30% harder than 1. We suggest this stiffness for player that weight is more than 80 kgs and with powerfull legs :).

About the full foot pocket we produce only the stiffness 2 but every players can use the same because the shape of the foot pocket is less hard than strapback.

3

In terms of overall performance, how would you compared the full foot with strapped one?

It depend by the swimming style of the player but he open heel are lighter and harder than full foot pocket so normally faster.

4

We can wear fin keepers with the strapped one?

It’s not necessary :)

5

how are they different in terms of durability?

We registered than the open heel is more durable than full foot pocket

6

The edge around one could peel off after being used several times.

Yes, it could be caused by the swimming style. However we normally supply the substitution edge and rail with the fins.

7

Full foot is longer than strapped one?

On average 5 cms longer.

I live in Belgium so how about the shipping costs? Can you make me a price?

What is the shipping cost to New Zealand?

My shoe size is 43, wich size do I best take? 43-44? (I have socks so if they are a little to big, no problem...)

The open heel 43-44 is perfect for you. Probably you don't need of a sock

11

The fins are guarantee or not?

The fins has guarantee for factory defects for one year but, time by time the company reserves the right to verify the nature of the break.

What the difference between Glass Fiber and Carbon+ fiber?

The Glass fiber is a little bit heavier and cheaper than carbon+. Carbon + is a composite fiber made by a multi-layer of glass-fiber and carbon fiber.

13

What is the life durability of your fins?

At the moment, after one year of distribution we never registered broked fins of the open heel foot pocket. The edge normally need maintenance but the blade are very resistant to the use.

About the full foot pocket instead we registered 4 pairs of broked blade but users reported that they broke because an accident with other players. The full foot style never broke the edge because is integrated with the foot pocket.

The fins are in order with the CMAS rules about the plastic layer around the blade?

The fins, as well as we provide, are not in order with the CMAS rules. But, simply attaching a sticky film on the blades, you can play the official tournament. In future we are going to provide the film with the fins.
