Cabelas meindl boots I believe they’re like 200-400g thinsulate. Just says insulated made in Germany but doesn’t say the amount of insulation but that is what I believe they are. Size 10.5 They were bought seven years ago took to Idaho five times for one week each time very good condition oiled every time they were used, Lots of life left in them ended up going to a size 11 so I could wear my normal thick socks. $100obo located in elma wa can ship on your dime
