fins rub on top of foot

[Hank49]

Depending on the material the pocket is made of, you can custom fit it.
I had a set of Pathos footpockets with a set of carbon fiber fin blades. I have a bit of a high arch and the Pathos pocket was a bit....flat, causing pain on the top of my foot after 4 hours of free diving.
So I dipped the pocket in boiling water for a few seconds (15 or so) and softened it up. I then put the pocket on my socked foot, let it expand and take the shape of my foot, and dipped foot and pocket I to cold water.
The shape worked great but after a couple years, the pocket slowly started going back to its original shape.
Some loved the Pathos pocket. I like Beauchat. Natural fit. I guess the conclusion here is, find a pocket that fits you naturally.

Although perhaps not as obvious as I'd like or perhaps I'm just used to looking at
these things with nothing original to compare them to and photos are just photos
but

I have moulded a bump above the toes also broadened the pocket substantially where a broader bit should be included an offset to cater for the bridge of the foot and especially moulded a substantial curvature at the top lip of the fin, the culprit that applies pressure and damages the sensitive nerves at the top of your precious foot which in my case have to hump around 132 pounds a piece for a while to go yet.

Still a really good idea to buy booties with a rubber panel on top of the neoprene

Ok these are of monprene compound but the stretching system is pretty much the same for most other combined compound fins and plastic with rubber being more stubborn

Having stuffed them full with whatever you have available that may replicate the shape of your earthly conveyancing devices, plonk them in a pot of boiling water (that I would suggest is not still on the burner boiling) leave for one minute and then dunk douse or hose with cold water for ten or twenty seconds

You really do have to hammer twist and contort that stuff to get it all in there

You see you have to stretch them more so they spring back less

Gone too far?????????

You can shrink or remould with a quick dip if required

I did deliberately not dunk past the hinges of my seawings because I didn't

Repeat with variations until satisfied and keep your water boiled

one boiled = one fin = reboil for next fin


Pretty good hey and you'll never never know until you have a real go


and now I have left and right fins to match my clomps

and trim your sharp moulding edges off


Willing to travel ha ha ha ha ha ha ha!

I have a similar problem with raised instep - only the difference is that I don't get a blister but pain only. So the socks solution is not applicable. I wonder whether the hot water and reshaping the foot pocket will work. The fins are Apeks RK3 - very tough material. I was also thinking of cutting a hole around the pressure point to redistribute the pressure on larger surface but my concern is that if it doesn't work, I won't be able to sell the fins.

 

[happy-diver]

You will add a new sharp pressure point for the circumference of the hole

Ya, don't cut them.

What kind of bootie do you wear?

I'm put of ideas. I thought you might need the extra rubber but I see your bootie has that.

Have you tried the lycra socks? I know that you said that you don't get blisters, only pressure pain.

I get the same. It wasn't as bad when I had booties like yours.

The only other thing that I can think of is some kind of jell guard but how would it be attached?

Happy-diver has an interesting unusual way of explaining things, that can be hard to follow. That said, he does have some good ideas if you have the code.

I know two ways to change fins overshoe.
First I`d described here: OMS Slipstream - overshoe rework

This way is best suitable for plastic (monoprene, or similar) fins. Not good for rubber fins.

Second way is suitable for any kind of fins: Shoe laces

Good luck!

Has Slav engineering gone too far?

P.S. I'm Slav, too.

it is not "Slav" engeneering It is just well forgotten old...

P.S. we have same type of modern commercial divers fins
