@WilliamNB I've tried all these (and even winter boots with overshoes) but no luck. I'm sized up in the winter boots, but the heated insoles don't work either and they don't leave much wiggle room which doesn't help. I think I just have poor circulation. I can just about manage an hour and a half before it's painful. I'm going to try some reynaud socks next to see if they're any better. Annoyingly my hands are just fine on the bike!
