Advice Best Insulated Boots for Walking on Icebergs?

Dear fellow wanderers, I'm planning a trip to Greenland for the Spring Equinox this March, and I need some advice on the best insulated boots for walking on icebergs. I want something that will keep my feet warm and dry, but also provide good grip on icy surfaces. Have any of you had experiences with specific brands or models that worked well for you in similar conditions? Any tips would be greatly appreciated!

For walking on icebergs, I'd recommend looking into boots with a high waterproof rating and insulation designed for sub-zero temperatures. Brands like Sorel and Baffin are known for their durability and warmth in extreme conditions. Make sure to check for a Vibram sole for excellent grip on icy surfaces. Have you considered the weight of the boots, as lighter options might be more comfortable for long walks?
