Hi Adi
TFG from Fishtec have some absolutely cracking waterproof boots on offer for £24.99. I have some and they are the best footwear that you can get your hands on for the price.
I don't know your size, but I have a pair of size ten Skeetex boots in mint condition with removable thermal liners just sat doing nothing. I also have a thermal and waterproof all in one suit that I have never worn, and never will wear since my wife bought me one of the Trakker coats you tried on at Wickersley (and yeah, the sizes are very generous).
You are welcome to them if you would like them. Just let me know. The boots have rarely been on my feet and were nearly £70 when I bought them, so they are top quality and would last you a good few years.
Regards
Stu
