I have tried Garneau (the earlier versions) which were so utterly useless they were actually amusing?
Goretex socks, these are better and do keep out the puddle splash but as others have stated will not prevent water p33ing in from above; does help if they’re tight. Also, I have found my feet/socks quite damp from sweating using gortex socks + toes still get cold due to lack of insulation – tight fit compounds this.
The ‘best’ option i have found to date are merino socks and a pair of Shimano MW 80s. The ‘wet suit’ cuff seems to provide a bit of a buffer to retard the rate of soak-age moving down the sock (helps if your sock is not showing above the cuff).
Funny, in the 15 years of walking (UK) in the hills I never used goretex (foot related) products- I suppose the movement maintained foot temperature….which is the main problem for bikers.
If it were me, I would not p1ss (no pun intended) about, save up and get a pair for MW’s. They’ll keep you warm, dry(I don’t know the limit on this aspect, say light to medium splash/rain)and are SO much better due to the reduced post ride faffing which is inevitable when using gortex socks.
Good luck with it, if you find the ‘Holy Grail’ of dry warm feet in any condition please post back 😆 😛
