MXZ304 Wide Mountain Bike Shoe

As a dedicated winter rider who pedals up frozen streams and across snowy singletrack, you know how important it is to have warm footwear that protects your feet from the elements. Lake was one of the first companies to make a dedicated winter cycling boot, and the new MXZ304 is their best one yet. A larger BOA dial is moved to the front of the tongue, making it easier to use with winter gloves and providing a more even tension across the top of your foot. Otherwise the construction remains similar the previous model, consisting of highly weather-resistant Pittards leather that molds to the shape of your foot for optimal comfort, and a heavy-duty Vibram outsole that provides maximum traction both on and off the bike. Plus, they're filled with lightweight Thinsulate insulation, keeping your toes warm when you're out in the snowy woods for hours at a time.

  • Winter cycling boots with a high-volume fit for wider feet
  • Larger boa dial allows easier adjustment with winter gloves
  • Pittards uppers block the elements and mold to your feet for comfort
  • Durable Vibram outsole finds traction in icy conditions
  • Outlast liner regulates temperature and prevents clammy feet
  • Thinsulate insulation keeps your toes nice and toasty
  • Winter last is wider and taller to accommodate winter socks
  • Lake recommends sizing up 1 - 1.5 sizes if using with thick winter socks

How to Measure:
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.
Step 2: Length measurement.
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.
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 actual length measurement to get recommended size.
Please Note: for accurate measurement please obtain a 3 digit millimeter measurement. Accurate measurements cannot be obtained from only 2 digits.

Saved my ability to ride in the winter

My extremities run cold normally - hands and feet - which has always had a negative impact on my ability to enjoy winter sports in CO. I would still partake, but I would be miserable half the time because of the cold. These Lake shoes have changed that to a level I never thought possible. Yes, I still wear two pairs of socks, but my feet now stay warm the entire time I ride. Rode for 3 hours the other night in 20 degree temps and my feet could've gone another 3 hours if my legs weren't dead. If you struggle with cold feet and need a solution, I highly recommend these bad boys. They are comfortable, warm & dry, easy to get on/off, and the Boa system allows me to tighten/loosen them for a perfect fit. Definitely order one size up so you can wear thick socks and still move your toes around.

Just curious, what kind/type of socks did you wear with these shoes? I wore Rapha merino socks with these shoes and my toes started getting cold after 10 miles ride. The temp. was at 25 F. I will try heavier socks...

I love these boots. Super comfortable, easy to get it with Boa system. I rode in sub zero temps and my feet stay warm. Most definitely recommend them. Since they run true to size, I bought a size up to wear with heavy socks

NOT for wet conditions

Rode in F 33/34° snowy weather. Snow melted and roads were wet. Shoe started soaking through about 20 minutes and feet wet after an hour. The tongue is NOT gusseted; ONLY attached/sewn at base. Water leaked through under flap, around the tongue. Deeply disappointed- have no idea why tongue would not be gusseted. Boots soaked through on a second ride with snow and wet roads at 30 ° F. Had bibs OVER boot top to keep water from running down legs into boots. Warm in 27° F and dry conditions. Have ordered another pair of boots for cold AND wet conditions.

Joseph I... Good review. Can I ask what you 'ordered' that would work for both cold AND wet conditions? Thanks!

Worth the money

I have been riding in the winter for a couple of years now. I have used shoe covers and/or toe covers for my road shoes. They are okay for me down to about 40 degrees. However, below that, it would get a little cold even with using electrical tape to cover cooling vents and chemical warmers. A friend told me an older model of these boots “transformed” his winter riding experience. I bought these new ones, and completely agree. I can use them even as warm as the 40s and be super comfortable. I bought a half size up and got the wide version for my wide feet (my other shoes are not available in wide). I am not a fan of the flap that covers the boa laces in terms of getting in and out of the boots, but it probably helps with keeping out the wind and snow. The boots look large, but are surprisingly light-weight. Feels like maybe 1.5 times the weight of my PEARL iZUMi X-Project P.R.O. shoes, which are very light mtb shoes. The minimal added weight is completely worth it unless maybe if you are in an actual race.
