I've got several seasons in with my Lake Winter MTB Boots and they have to rank near the top of my favorite equipment of all time list. I've once again been wearing them on my commutes and find them to be as comfortable as they are warm. Temps have dropped into the single digits Fahrenheit (a dozen or so below Celsius) and I have been plenty warm every day. My commute is currently just over 16 miles or 26 kilometers for those using the more rational measuring system, which takes me just over an hour with the extra gear and studded tires. These boots also have reflective markings front and rear so they also help me show up in traffic.
Now as good as the boots are, I do use chemical heater for longer rides when the temps are 30 degrees (f) or lower. I also put on neoprene shoe covers for zero and below but they keep my toes warm. Warm toes are good for everyone but for someone like me that experiences Raynaud's Phenomenon,
warmth is both difficult and critical to maintain. My toes can go numb sitting around the house in the summer if the air conditioning is set a bit too high. OK, the Wikipedia pictures are overly dramatic (where did they find orange and bright red people?) for how it affects me mostly due to my aerobic fitness level as that helps greatly.
The bottom line, however, is that even though I have had some issues with them, the Lake Winter Boots have opened the winter season to me for riding and I can't imagine winter riding without them. Oh and they are clipless so along with the warmth I can still maintain my full power-stroke which is sometimes all that keeps me upright in the deeper snow.
