Don,
Like Jon well said they are very similar to the OMER and the Sporasub ones, with the same system of two screws to attach the blade and the lateral rails in to the rubber.
They are a little wider than the OMER; they are really exact to the Technosport footpockets. The thing is that there are a lot of footpockets of different brands that they started to be fabricated by the same people in Italy. The first Spora, Technosport, former SULA fins from the people of Elios, and Spetton are made with the same molding.
The last time that I went to your house I was carrying both Technosport and Spetton footpockets, next time I show you properly.
Leaderfins uses Omer or Spetton for their fins and Monofins, but they can send you the ones of your preference. With the Monofins they weld to footpockets in one cutting two of the rubber rails and leaving only the two in the exterior sides.
Both brands will be capable to receive the blades with and without angle that Leaderfins manufacture, as well as CT’s, Cressi, Spora, Matrix, XXone, among others. The only blades that I do not know for sure are Picasso’s because they use only one screw.
Really we do not import a lot of full fins to USA, normally we sell blades and them you use them with your own footpockets. If you want spetton pockets I can provide them cheaper directly from Spain because we represent spetton directly in USA and if you need OMER I can give you the contact of Mark Laboccetta of Technosport, he is the OMER distributor here in USA. It will be cheaper too.
I like to offer to my clients the best technical and economical option at the end they will become your friends. It is stupid that you have to pay for some footpockets that travel from Spain or Italy to Estonia and them to USA.
Regarding the Leaderfins blades there are totally custom made blades you can choose materials, size, stiffness, blades with and without blade and in some models even color or camouflage patterns, and you can also add the graphics that you want. So it is almost impossible to have in stock all the different options. We will try to maintain at least different stiffness that is the variable more important in order that if you live close to me in Texas or to Pablo, my partner in Florida you can test them.
But you do not have to worry you are in the corner!!!!!!!!!! And you already have blades from Specialfins that gives you a really good idea of what to expect regarding the stiffness. Remember that both Specialfins and Leaderfins came from the former Sebak fins, so they use similar fabrication techniques.
Ok we will in contact
Cheers
Ivan
