 Lake MXZ-400 Winter Cycling Boot

Need a boot warmer than the Wolvhammer without the additional bulk of a double boot? The New MXZ-400 Winter Fat bike boot from Lake has arrived!  Lake was the first cycling footwear brand to introduce a cold weather boot over 10 years ago with the original MXZ-302 and has now created a bigger brother for the ultimate in warmth and with less bulk! This new MXZ features 400 grams of Thinsulate Extreme insulation good for -40c, waterproof and breathable Pittards leather construction and 2 easy adjustable Boa laces so you can dial in the fit you need. The higher ankle helps with hiking through the deep stuff and the new out sole features anti slip intelligrip pads for ultimate ice traction. We think this is the ultimate winter boot for the rider serious about fit and performance in all conditions but warm ones.

    First off , Thank you for the great service provided.Secondly, It is a must to have winterboots for cycling.Size wise, i ordered a size 48 and it is a 48.I always strive for the best, its all or nothing. This boot is warm and has a very comfortable fit on top of being extremely light. I use to race pro and i also done a 20000km bike trip in all conditions. I also worked in the Yukon outside all day long. As a result i had a severe frosted bites on my feet . Trust yourself first. But if this can make the difference between riding and not riding your bike during the winter months . Well… then i have served my purpose.Happy ridding ??
