I've always had a strong pulse, and have never had frost bite/nip. In fact, I done plenty of climbing in leathers without really noticing the cold before, but for some reasons these boots that I thought would be toasty had my feet numb (they are a good fit and I wasn't wearing crampons).
Anyway, thanks for the ideas with the inserts...I'm going to give that a try.
Does anyone have Scarpa Alpha Ice boots? What do you think?
