Dvalliere Hello...And I know exactly what your going through...Some people are actually considered cold handed and cold feeted..When either of those gets cold for me, it is by far the most hunting ending episode i can expierence...Cold feet and me doesnt go lol..Well, you started off by going with uninsulated boots which was a big mistake, and yes insulated boots can get pretty damn pricey. About a year ago I purchased a pair of Rockey hunting boots with an added 1,000 grams of thinsulate in them that cost me around 150.00. With temperatures above 40 my feet do stay comfortably warm, but when the temp plumits these boots suck...Although there is a solution to mine and yours problem..First off get some good socks, which you probably already have, and always double sock your feet if its not to uncomfortable. Second, one thing that has helped me time and time again and always works is get some heat insole inserts that are made by I believe called hot hands. Their those fabric sacs that contain almost like a sand that produces heat, their very cheap I believe 1.50. When shaken are simply by taking them out of the package..just insert them in to your boots and "Bam warm footsies". Hope this solves your problem
