Ok,

I am looking to buy some hunting boots, I am use to using just insulated rubbers but with the more walking I am doing these days need a good pair of boots,

The question I have is how much insulation should I be aiming to get,

I tend to hunt in the -10C to 10C (about 15F to 50)

I see 400, 800, 1000, 1200, 2000,

Thanks
Jeff
