I love the Brooklyns. This is the first winter that I have footwear that don't hurt my back when I walk, are comfortable, AND are warm. Mostly I was missing the warm part. Like I say in the review, most minimalist footwear have either too thin a sole, too little insulation, or both to keep my feet warm in -20C. Here in Alberta, it's -20C A LOT.
Although I mention in the review that the Brooklyns don't grip well on ice, I don't have a single pair of minimalist footwear that does. Now I think the challenge to the industry will be to design a pair of comfortable, minimalist footwear that is good for -20C and can grip on ice. I think it's a tall order.
