I bought these as I am currently doing data collection on hill sheep and with the surprise bad weather I needed to do something to try and keep my feet warmer (besides two pairs of socks and fleece welly liners!). The word "fiery" perhaps lead to slightly high expectations. They were warm at best, and only for about half an hour. Maybe the conditions were just too cold (around zero?!). I bought 4 pairs and all were the same, and at one point one of them burst which meant I had a gritty foot all day as well as orange socks and despite washing it out the inside of my wellie still turns my socks orange. Oh well! I won't buy them again!
