rain can easily trickle in from the ankle area. . . . They are still drying out in the radiator, three days later....
. . . have you got a solution?
My solution to the OP is:
Waterproof socks (eg Sealskins - which by the way size correctly - don't get them one size too small like most socks - they scarcely stretch at all)
Bioskin calf sleeves - retained from a period of soleus pulls and physio treatment - rough quote:
"The Bio Skin material ensures the sleeve won’t slide down the leg, no matter how vigorous your activity, and, to maintain comfort, Bio Skin’s material is thin and breathable allowing perspiration to evaporate keeping you cool and protected."
These are worn over the socks and ensure nothing dribbles down into the socks.
Bib-tights (no stirrups: stirrups mess with my insoles/sole)
Winter boots (mine have neoprene cuffs which can be got reasonably tight with velcro fastening)
Drying boots: Insoles out, scrunched up newspaper, renewed as often as reasonable.
IMO (
@mynydd post) if tights are a good fit just above the ankle (as designed) then you will stretch them massively/destructively if you try and get them outside winter boots.
