In reply to avinash1981:
My first pair of plastic boots used to belong to Al Rouse. They've been beyond usable for many years and I finally lobbed them in the bin today. They weighed a ton compared to what we have now and I can still remember walking up to the halfway lochain on the Ben in a pair of trainers, before switching to get my ankles battered in them!
I gave mine away to a guy doing a 'once in a lifetime' trekking peak in Nepal. Must be more like him out there. Trekking companies like KE Adventure also rent out plastic boots, they might be interested to take them if they are OK. (And I seem to remember they looked OK in 2012 )
They are useful on the first day of a winter ML assessment where you are standing around a bit and then have to kick steps etc. With 1kg+ on each foot, you can kick steps in boiler plate ice! Apart from that they now fall into the same category as Tweed breeches.
I sold mine just last Xmas time. The chap paid 30 quid for them although I covered postage out of that so maybe made 20 quid on them. He was really happy with them as they fitted him well and he only needed them for a couple of days near the summit on an upcoming trip to Peak Lenin, so obviously way cheaper than other options. So anyway, you might find someone in a similar position.
