I use the fourth element hotfoot socks, 2-4c during winter and they're fine for one hour dives. Feet are not precisely super warm at the end, but at least no frostbite...
 
I also have freezing feet, but with the right set of socks and some other precautions I am not that cold anymore even though I do long dives in the arctic year around. I have tried most things including Santi socks, DUI socks and some other types as well. A few of them were too lofty and bulky, which caused the boot to be tight and thus my feet were cold. Now I use Aclima Hotwool socks as the first layer and then a pair of home-knitted socks made of high quality wool. I put the Swedish link for you below. There are probably several retailers carrying Aclima in Sweden, but similar thick socks should also work. It is really important that none of the socks are super tight and constrict anything, and also avoid putting too many or thick socks onto the feet so the soots on the suit will be tight. You need air/gas and some wiggle-room to keep the feet warm.


I would also maybe suggest a warmer undersuit of 400g Thinsulate or something as keeping the core and rest of the body warm aids the feet and hands.

I normally have quite cold feet even before I get in the water. At least in wintertime. I live in Sweden:/

This is one thing I absolutely reccomend you adress, and I can warmly reccomend scooter boots. I always bring my scooter boots except maybe from June to August. I do all preparations wearing them, and wait until the very last minute, when all my buddies are also ready to suit up, to get out of the boots. When I do that I then take on the socks I will wear for diving as the other socks worn during rigging and/or carrying stuff to the water might have become slightly sweaty.

When I'm out of the water the first thing on my list is usually to get out of the suit and into a thermodress and my scooter boots before doing anything else. Doing that helps me to regain warmth to my body and feet and avoid getting colder.
 
If your feet are damp and not dry when you get out of the suit then you are dealing with sweat that is cooling your feet. If not then compression or lack of insulation is the problem. The easiest way to deal with sweat is to put a very thin nylon sock on your foot first, then insulation. The nylon will allow the water to wick away from your feet and provide an air gap between insulation and foot. I used this method for downhill skiing and it works well.
 
A 300g undergarment seems pretty thin for that water temperature. I wonder if your cold feet are just a result of your legs being too cold.

I won't dive less than a 600g undergarment in 16c water, but I'm a wimp about the cold.
