Does such a thing exist? I have to wear wellies at work. I hate the feel of wellies with ordinary thin socks so I wear these thick socks called Heat Holders. They cushion my feet nicely but at the end of the day my feet and the socks are very sweaty and as a result, stinky (I also only have one pair of these socks so it’s getting very annoying having to give them a quick hand wash at home every day!). I work in a pretty warm and very humid environment so you can imagine how much my wellies smell after 8hrs of my feet sweating away in them 😬
