+3532840609The MX239 mountain biking shoe is the latest version of one of our all-time favorite mountain biking shoes, for riders hitting the remote and technical trails. This evolution of our legendary MX238 is updated to include an integrated tongue to the medial panel of the upper for a firmer foot hold, ensuring that power is maximized into forward momentum through improved stability – a vital ingredient on loose and technical terrain.
The MX239 MTB shoe comes with a new fiberglass reinforced internal heel counter, creating a more stable heel hold, and has more spacing between the two BOA® dials to give greater zone adjustment to the forefoot area. It takes one of our favorite off-road adventure cycling shoes to a whole new level of comfort, fit and performance, with modern styling as standard. Add to this the Mountain Competition real rubber sole, and you have a mountain biking shoe that’s ready to take on any challenge.
MX Competition Last
Featuring a larger toe box & tighter heel than the Comfort Plus Last and with slightly more overall volume than the Sport Last. Exceptionally secure for hard riding/racing with enough room in the toe box to prevent binding when running up inclines or negotiating those tricky technical sections, while the wider toe box gives your feet a more natural fit and platform.
Our Lake MX Competition Last ensures that the MX239 mountain bike shoe is designed to maximize your performance when riding off-road adventures or racing on the rough stuff – for as long as your adventures last.
Outsole
The MX239 comes fitted with our Lake Competition 100% Carbon Fiber Sole, alongside our Mountain Competition real rubber sole, and with extended protection for excellent ground stability. This added outsole protection helps to ensure stability on all types of surfaces, while giving necessary performance on the pedals. The rubber extends over the front edge of the shoe, providing you with important protection against wear and tear on loose terrain.
Upper
This latest high-performance off-road shoe is available in Clarino Microfiber or Helcor leather upper with mesh and Outlast heel lining. The Helcor Abrasion resistant leather is specifically designed to be extremely durable against rubbing, scrapes, and scuffing. The Clarino Microfiber is super tough and resilient to the arduous wear and tear of long rides on all types of terrain, maintaining its shape and stability, while being lighter than full-grain leather and more durable at thinner gauges. This allows us to give you a cycling shoe that remains stable in all riding conditions, and which will stand the test of time.
With your foot wrapped in our legendary Lake comfort, the Outlast temperature regulating heel and tongue lining offers a luxurious foot feel, while maintaining a breathable, durable & firm grip to your foot.
Closure
BOA® Fit System Li2 Dials. The Li2 dial is the most advanced platform in cycling, offering a precise, micro-adjustable fit in both directions and designed to resist abrasion. There is not one element that can take credit for shoe fit on its own. Closure and comfort come down to several details, which is why here at Lake, we take time to design shoes with what we believe to be the best comfort and closure systems. The dual BOA® fit system is not unique to cycling, but it is how we use this dial system in conjunction with our pattern work, our world-class shoe Last and our selection of superior upper materials that make this system work.

ONE SIZE DOES NOT FIT ALL.
Lake Shoes
Lake's mission is to make the best fitting and most comfortable high performance cycling shoes in the world.
Lake is one of a small few brands who focuses on the foot first crafting a comprehensive range of shoes to fit all foot shapes and riding styles.
This theory goes beyond materials & construction methods to the actual foot form (the “last”) around which a shoe is built to determine whether a shoe meets a particular need. Instead of trying to make one or two foot shapes fit every rider, we have created a variety lasts to meet most riders needs.
4 Step Fitting Guide
Fitting Guide

Step 1
Measuring Your Foot
Tips for accurate foot measurement
- Take your foot measurement in a standing position while wearing your cycling socks.
- Please obtain a 3 digit millimeter measurement.
- example: 267mm or 26.7cm will provide the correct amount of data.
- Two digit measurements, like "26cm", does not provide enough data to determine size.
Step-by-step
- 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.
- *We recommend adding 5mm onto your length measurement before checking the size chart.

Step 4 Review Shoe Lasts
MTB/Gravel Lasts
Shoe lasts are like a template used by shoe manufacturers to ensure consistency and accuracy in shoe production. Lake Cycling has a variety of shoe lasts built for a variety of conditions. Read more below on each.
MX Sport
This last features a larger, more roomy toe-box than our Comfort last while providing increased foot control through the heel & saddle of the foot. The resulting fit is designed for aggressive riding while remaining comfortable to wear all day. Ideal for couriers, adventure cyclists & anyone else who wears their cycling shoes for long periods of time.
MX Competition
Featuring a larger toe box & tighter heel than the Comfort last and with slightly more overall volume than the Sport last. Exceptionally secure for hard riding/racing with enough room in the toe box to prevent binding when running up inclines or negotiating a hike-a-bike section. Designed for performance riding & racing.
MX race
Featuring a slightly narrower toe box & tighter heel than the Competition last and less overall volume than the Sport last. Designed for a slimmer fit & most suitable for racing.
MX Comfort Plus
Our Comfort last is designed to provide foot control while pedaling without restricting the foot during off-bike activities. With a feel similar to traditional athletic shoes, this is an excellent choice for commuting, on & off trail sport rides & gentle terrain trekking.
Road/Triathlon Lasts
CX/TX Sport
The higher cadence & longer ride times which characterize road cycling require excellent foot control to avoid hot-spots & numbness. With a much closer fit than any of our off-road lasts, our Sport last cradles the foot securely to prevent any unwanted movement. This last features a precisely fitted toe-box, high arch & mid width ball girth.
CX/TX Competition
With a profile specifically designed for very high-cadence riding & higher pressure, our Competition last features a more curved profile than the Sport last. The main differences include increased toe pitch & heel lift, a tighter heel & a slightly wider ball girth to allow the foot to expand under high pedaling pressures.
CX Race
Featuring a slightly narrower toe box & tighter heel than the Competition last and less overall volume than the Sport last. Designed for very high-cadence riding & higher pressure and a slimmer fit.
CX/TX Comfort Plus
The Comfort Plus last has the most generous forefoot platform of all of our CX lasts. This last will accommodate a multitude of foot shapes and allow for toe splaying. Made for those riders who struggle to find an unrestricted shoe for the shape of their feet.
Winter Lasts
Winter
With a much wider & taller toe box than our traditional lasts, the Winter last allows the foot to maintain proper circulation even when thicker socks are worn. Our winter last is the standard for winter cycling footwear.
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.
