That’s not new to the Russian army. I watched a documentary about the Russian army decades ago and they were using the same cloths. Sock tech eludes Ivan.
Yes I watched a documentary of how Russians dressed their military for winter - these were standard issue. Was interesting to see how they were better than socks. ...annd they were trained how to properly wrap them.
I’d like to see your feet if you’d use a regular stock with a jack boot.
