Lake MXZ305 Winter Boots
What makes the Lake MXZ305 Winter Cycling Shoes stand out is their unique boot shape and construction, designed to trap warm air, nature’s best insulator. The pattern prevents restriction of blood flow, allowing your feet to generate and retain their own warmth. This ingenious design ensures your feet stay warm and dry throughout your ride. The highly breathable leather upper and temperature-regulating lining wick moisture away before it can freeze, maintaining consistent comfort even in sub-zero conditions. With its wider and taller Winter Last, you can wear thicker socks without sacrificing circulation or fit - a crucial advantage for winter cyclists.
Tough and protective
The American full-grain leather upper and German Helcor toe protector offer unbeatable durability and weather resistance, while 200g of Thinsulate insulation and Outlast lining regulate temperature and wick moisture for all-day comfort. Finished with the BOA® Fit System, easily adjustable even with gloves, the MXZ305 delivers a precise, glove-like fit built to perform in the harshest winter conditions.
Enduro sole unit
The MXZ305 doesn’t just keep you warm, it keeps you confident and stable on any surface. Built on Lake’s Ultra Bomb-Proof Enduro Sole, the boot features glass-injected tread inserts that grip virtually all terrain, while remaining SPD-compatible for efficient pedalling.
The Lake MXZ305 Winter MTB Boots set the gold standard in cold-weather cycling footwear, trusted by riders who demand warmth, comfort, and performance in every pedal stroke.
Care:
The uppers are treated with a durable water-resistant (DWR) coating that will wear away over time. Lake recommend reapplying a DWR spray 1-2 times a year for moderate riders and every 2-3 wet rides for daily riders.
Pedal Compatibility
These off-road cycling shoes are compatible with MTB and trekking pedal systems utilising the 2-bolt cleat system, such as Shimano SPD, Look Trekking and X-Track, crank brothers Candy, etc..

Take your foot measurement in a standing position while wearing your cycling socks.
Step 1: Trace your foot onto a sheet of paper. After you trace your foot take a ruler and make a line to mark the furthest point on all four sides as shown below.
Step 2: Length measurement (Points 1 to 2 as shown below). Use a millimeter ruler to get the measurement of the longest distance from heel to longest toe (first or second toe).
Step 3: Width measurement (Points 3 to 4 as shown below). Use a millimeter ruler to get the measurement of the widest distance of foot from side to side.
Step 4: Repeat steps for other foot as your feet may be different sizes. Typically you will want shoes that accommodate your largest foot the most comfortably.
*Add +5mm to your measured length to get correct shoe length.
