Cheers Gone for some of the gaiters @Doomanic recommended - I hope they don’t make me crash more though ??Despite his professional sounding advice, I'd avoid trying anything @outerlimits has suggested. For starters, unless you're a plumber, you're going to be looking at some big bills down the line and if you have a podiatrist, you won't have them for long.
I think seal skin socks have been suggested, the gaiters linked by @Doomanic are supposed to work well. Mentioned in previous posts were also the Aldi waterproof socks, when they have them in, are supposed to be as good or better than the seal skins.
I wore my waterproof walking boots today, which were fine until I went for an early bath and then I just had two small buckets of water attached to my feet for the rest of the ride.
