3m review update: Awesome shoes for hiking and trekking, does put strain on the Achilles when sitting for long periods of time.
Grip on the shoe is great, always felt surefooted, even on icy hikes.
Waterproofing is on point never had issues in snow or puddles.
Warmth, combined with some good socks, toes always nice and warm. Have not used in very hot temperatures, but mid 30 degrees celcius no issues.
Comfort, great when walking and hiking, feet feel very supported. Issue with sitting as the top back of the shoe will put pressurer on your Achilles. Would suggest not doing up the top stud on laces to mitigate this abit.
