Doh.......
Even the cheap Aldi ones are great..... - they keep wind chill off, they aren't waterproof, but it saves me using my BBB Hardwear Water Proof nasties that cost too much.........they cost £30 plus, but are waterproof............
Very essential kit - not just keeping feet warm.........
Waterproof ones stop water getting in and rotting shoes, at worse or minimum...making shoes smell like the local abattoir.............. Hence I use my waterproof stuff lots..........
Use em......... nice fitting shoes are hard to find............. look after them..............
