The Lake MX333 mountain bike shoes are best known for their incredible fit. These have been upgraded to now feature Lake's new sole and Carbitex arch support panel, resulting in a more secure fit. Lightweight and extremely durable, the new MX333 is perfect for all mountain bike racing.
The upper is made from lightweight Clarino Microfiber or extremely durable Helcor leather, combined with a medial support panel for a secure fit. Drawing inspiration from the CX403, the MX333 has the same Theraform technology. The heat-moldable carbon gives the option to customize the fit of the heel cup. This security increases stabilization and power transfer.
The sole comprises the Lake Race Carbon fiber sole coated with durable and grippy TPU lugs with provisions for spikes. Finished with the Li2 Boa closure system. These all combine to produce a secure and extremely comfortable fit.

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.
