Fiberglass Hockey Fins

For 170 Euro you get a fin made to fit your foot, although of course I can't make any statements about material quality since I am no expert and haven't used them for long enough yet to have an educated opinion.

Sounds great, very interested to see what you have come up with....

Jols, I was talking about footpocket moulded for your foot, not just an option of diferent footpockets mounted on the fin. Anyway, thats still long long way ahead for me, but its possible to make footpocket completly custom, thats for shure!
In any other way - technollogy of making fins, that is not possible or is too expensive and takes too long to make it, so the only option left is different inserts either glued or removable...

...as much as I know about these things.

So was I.

When you order you provide measurements of your foot and a footpocket is made to measure (glueing rubber) for you.

Again...I ment molded footpocket! The right mold, and the left mold! No measurements, simply your foot inside your fin with all detailes. Best fit possible. No rubber inserts, no general mold, simply your very own custom footpocket.

Thats a very big diference in production, and a small but perhaps significant dif. for player. I hope I'll be able to make this possible. For now, I dont see why not.

Personally, I think that footpocket is the key factor for high performance fin.

That would be fantastic if it is possible...

Simply insert foot here, and rubber at 250 degrees will be injected into the mould under high pressure....

No...

Mold the foot with special skin friendly moulding material, then..... then its up to me!

Flk is right, a quality foot pocket is extremely important. Any effort you exert that gets wasted because your foot moves before contacting the fin is gone, hence the use of wasted. I laugh at people saying they want to get faster and then put on a neoprene sock (or any non-stiff material). Um.... that just acts like a shock absorber and reduces efficiency. If you really like your fin, just get a smaller foot size and fit those puppies in. You'll see immediate results on speed, even with the smaller blade that sometimes comes with the smaller foot pocket.

So if I made a couple of porcelain feet and sent them in, a completely custom foot pocket could be made. That sounds like a winner. And without the scalding.

Oh yeah, and now they're broke.

...mmmm. obviously those assumptions are pretty debateable duck without some pretty detailed scientific testing.... but i do agree you have to have a well-fitting fin.

then again, take the ala foot pocket for example.... not 100% perfect but a size 42-44 fin will fit pretty perfectly to a size 11-12 (US) foot, in particular around and under the ankles etc and the arch of the foot... cos its nice and stretchy i guess. there might be a few mm of movement around the toes but pretty darned minimal, and if you follow ducks logic of movement with no contact equalling waste then its only a fraction of a second of waste at the very start of any stroke, such a tiny fraction as to be almost irrelevant.

i guess what i'm trying to say is, alas, leaders etc have shown that its possible to get a very good fit with a mass produced design (of course could be improved still further...)

...so possibly the added complications, time, effort and cost of custom fitting fins to a particular foot would outweigh the possible improvements gained in any performance boost.

but then again i guess it has to be done first to see what advantages it would have!


also just thinking aloud but wouldn't there be problems with the change of the shape of the foot between extended, pointed through the down stroke and say, fully flexed and drawn up as the foot would be while sitting stationary on the bottom, or through turns? surely the foot would change shape as its extended and compressed, as force is driven through it in the same way a runners foot flattens and expands on inpact with the ground.... and we're restricted to tougher material than can be used in running shoes. that skin has to be able to wrinkle or go somewhere surely... maybe you'll have to use a very flexible material otherwise the foot will be locked into a position that is great when swimming but uncomfortable while static or turning?

what do you reckon fk pk?

Custom-moulded footpockets would be the business! The other key is reenforcing it enough that the power transfer is direct. This is where the modern-style monofins really fall down.

If you want any ideas/advice/critique, send me a message. I'd be happy to help
