The code number in the Professional Soldier holds the size in several dimensions as it is worn with Breeches as part of Dienstuniform, so it fits better if you have thick legs, the Soldier Boot is cut wider as they wear trousers.
One notable drawback I've noticed with the professional soldiers boots is that its hard to break them in quickly. If you try to break them in like you would the combat boot, high DMS, (with the warm water inside the boot method) you end up actually unbinding the adhesive between the upper and lowers and your soles fall off. Speaking of lower soles, for the officer boots, they're pretty low quality. There's no shank and there's an abundance of voids within the construction that can lead to some irritations when walking for a while.
Are these designed to be worn with socks? Soviet jackboots basically require footwraps instead of socks. Great snag on those professional soldiers boots. They are hard to find in that good of condition at a reasonable price
NVA field socks were a Matt Grey, the socks for Service dress were a shiner grey... Foot cloths were issued and available in some Sealed Clothing underwear Packs
Yes. Footwraps are meant to be worn in combination with socks for these boots. You might be able to get away with a double layer of socks, but even if your size is right, any slippage of your foot inside them will probably result in some nasty blisters after a while of walking.
