+3532840609The MX21G is a sleek and modern classically styled cycling shoe that gives a low key look without sacrificing comfort or performance. Built on our Competition last and taking design cues from the MX238 Gravel, the MX21G is a great choice for those riders who appreciate the adjustable fit and secure comfort that laces have to offer.
The padded single-piece upper wraps your foot like a second skin, giving that legendary Lake comfort on the technical gravel grind. With the heel grip liner and the 100% Carbon Fiber Sole with Mountain Race X real rubber sole, you’ll power on through those rocky gravel trails.
MX Competition Last
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.
Outsole
Our Lake Competition 100% Carbon Fiber Sole ensures maximum power transfer, with stiffness and security for every pedal stroke. We’ve added to this our Mountain Race X real rubber sole to give secure placement and grip on all types of terrain.
Upper
Clarino Microfiber comes with an internal gripper heel liner helping to maintain stability. This ultra minimal upper is padded and wraps around your foot with ultimate adjustability from the laces, maximizing comfort and a secure fit. A rubber toe bumper adds protection to the front of the shoe, while the feet benefit from a naturally formed toe box.
Closure
Durable and easily replaceable Laces that offer Unlimited and Ultimate customization for fit and comfort, alongside a classic cycling shoe style. With ultimate adjustability, the laces wrap the single piece upper like a second skin.

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.
