Below are some further thoughts on minimalist footwear options.
Fleece- RbH socks
Leather- feelmax kuuva (n/a - in production)
Foam- custom 4mm intuition boot (n/a - custom)
Neoprene- 40 below overboots
Wool- boiled wool socks aka dachstein (make myself)
1) Fleece is not windproof, feelmax is not insulated, thus they cant be used alone. Together they would be a good combo. -VB, windproof, waterproof, insulated
2) intuition 4mm boot doesn't exist but the company likes the idea and may make one. Warmth is comparable to option 1) but lighter. -
3)boiled wool socks. Wind proof, very warm and likely better ground feeling then the other options. This is the only option which may work on ice without needing crampons. -windproof, water resistant, insulated.
4) RBH socks + overboots. VB, windproof, waterproof, insulated
I have read that wool has amazing grip. I plan to test this.
I don't climb in dachsteins anymore, but they were great on mixed
routes with a whole range of palming moves available if you dropped
your axes onto their leashes, as they semi froze to the rock/ice and
often enabled upwards progress when every other option had gone! I'm
sure these days other techniques would be used, but that's the point---
you make the most of what kit you're using and make it work for you.

From a safety aspect, wool’s texture offers significant friction on
snow or ice, aiding in self arrest situations. Besides being a natural
durable material, this added benefit of safety in the form of
friction, is completely unique to wool, and out performs from a
friction standpoint, even synthetics such as Scholler Cloth.
