With double the insulation and a cycling specific winter Last, the MXZ400 is the new standard for extreme cold weather cycling footwear.

Sizing Suggestion: For use with winter weight socks we recommend ordering 1-1.5 size up from your normal Lake Cycling shoe size.

Winter Extreme – This last features our largest & tallest toe-box for ultimate insulation in extreme winter conditions. The Winter Extreme last allows the foot to maintain proper circulation even when thicker socks are worn. What's unique about our last is the cycling specific heel, instep and arch shape that still maintain proper conforming fit to keep your foot securely in place while riding or walking without the need to over tighten. Our Winter Extreme last continues to forge ahead to comfort and warmth for winter cycling footwear.

Sub Zero rated rubber, Ice grip inserts. Wide platform rubber sole designed specifically for slippery conditions.

Double the insulation (400g 3M Thinsulate) and built on a cycling specific winter last, Pittards WR100 & Helcor abrasion resistant leather, waterproof membrane.

BOA® Fit System dual IP1 dials with reflective leather over-flap and Click-Fit Quick Release for easy entry and exit.

-5°F to 32°F / -20°C to 0°C

The uppers are treated with a durable water resistant (DWR) coating that will wear away over time. We recommend reapplying a DWR spray 1-2 times a year for moderate riders and every 2-3 wet rides for daily riders.

TOUGH and WARM

I sized up 1/2 to accommodate a thicker sock. The double Boa makes adjustments WAY easy. Roomy (but not sloppy) toe box. Built SUPER well. After many years of 303's - decided to jump to the 404's. Only bummed I didn't do it sooner! Warm, comfortable, easy to adjust, and TOUGH!

These Boots Rock!! Huge Upgrade

I have been using the Lake MXZ303 for many years for Fat Biking in the Winter. Finally took the plunge to upgrade to the MXZ400 and so glad I did. So much warmer! Love the uppers and the 2 Boa system. Day after Christmas when I got them it was around 32 degrees. Still wanted to try them out but was worried they might be too warm. But I was fine even in the little bit warmer temps and love everything about them. Can't go wrong with these Boots!!
