The Goretex socks thing was a bit of a long shot and deep down I knew they were not a long term solution. This afternoon I bought a pair of Scarpa Ranger II GTX boots from Go Outdoors for a reasonable £129. I am currently pre treating them with some Scarpa HS12 cream and Leder Gris clear. Hopefully I will be able to try them out on a walk tomorrow. Regarding the gaiters, you might strongly disagree with my decision not to wear my gaiters but I absolutely know where my old boots were leaking.... from the flex points near the toe. My gaiters don't come that far down and wouldn't make the slightest difference. Thanks again to everyone for their help.
