Quick review of some gear I recently picked up and have used on the ice:
Muck Arctic Pro Extreme boots -
Keeps my feet very warm. I've worn them out twice, in 20 degree weather only, with only 1 pair of smartwool snowboarding socks, and have not had cold feet. They are high boots and completely waterproof. No laces. Just slip on. They wear snug on my calves to seal off the elements. Need external ice cleats for traction though.
Kahtoola Microspikes -
Awesome traction! Easy to slip on and off. Any ice cleats are a must have on the ice right now.
Arctic Armor Plus bibs -
Keeps my legs very warm. The Plus bibs have a tricot (thin fleece) lining, in addition to the 3 layers of insultex (floating insulation). Very light weight and not bulky. Wasn't sure how much clothing I needed under, but I was more than fine with only my cheap long johns that are 50% cotton/50% poly. Yes, I know cotton is a no-no, but you need something to help absorb a little sweat/moisture because the bibs do not breathe well. You just have to unzip a little here and there for relief if necessary.
