throw toasty feet insoles in the lakes and chuck the stock ones
and you will not regret it

edit: holy crap ! I just went for another ride in them, in the woods on the
pugs..and had to stand around in snow a few times while I was
sawing 2 blowdowns...

the toasty feet prevented heat from escaping my shoe, and no snow melted
into the cleat. when I went to clip back in the cleat was fine. unlike the usual
ice block that forms and you have a hell of a time clipping in

honestly zero temp change when riding or standing in snow...toasty feets are teh ballz
