You realize that no one here inTeamEstrogen, will be cycling as far north as Edmonton. You'll beat me as the most Northern forum member unless we have someone in Alaska... If I were you, and not having cycled in any snow/ice for a long time, especially under very cold temp., make short trips....under 15 km., especially if very cold. You'll find it's enough of a spin and you'll be happy. Wear wind pants over leggings. I'm not the type of cyclist that cycles in boots. Too clunky for me. But might work for you.

Am in Calgary.
