Why We Like The MX146 Cycling Shoe

Cold and gray urban commutes are a little cozier with the insulated MX146 Cycling Shoe. The weather-resistant build keeps our feet dry and warm, while the rugged dial adjusts easily with gloves on. Fitting securely through the heel and midfoot, we maintain control on the ride, while the roomy toebox lets our toes splay and wiggle freely for optimal comfort in and out of the saddle.


  • Warm cycling shoe for cold weather rides and commutes
  • Rugged lugged sole provides hardwearing, slip-resistant performance

Really Good Spring/Fall Boots

I've used it several times

I've seen a few other reviews say they were only good down to the 40s, but I've never had cold toes even down to the low 30s. Well insulated and well built. I'm not crazy about the lacing system. The Boa works well but I'd prefer to control the lower portion of the boot individually from the upper. Having to crank down the fit around the ankle to tighten the boot below isn't ideal. In terms of fit, they're generous width, even in the standard fit. They do run about 1 size small tho.

Great winter boots

I've used it several times

I bought these after a cold ride where my feet were almost frostbitten. They work great for me with normal cycling socks down to about 35 F, then work great with thicker socks below that. Of course wind and sun change the equation. I have worn them up to about 50 F and my feet did not overheat. Coldest I've tried was around 30 F with gusty winds and my feet were a bit cold after a few hours but a lot better off than regular shoes with booties. They are tight and a bit of work to get into, but they have loosened up some and are a bit easier now. Check the Lake site for sizing up recommendations. I followed their recommendations versus my Lake road shoes and it worked well. The single BOA buckle works pretty well. More buckles would give a bit better resolution when adjusting the fit but I think the one buckle works well enough. I'm definitely glad I bought them.

Best mountain bike boot!

I've used it several times
Size Bought:
6' 2"

The MX146 is a terrific midweight boot (20~50F/7~10C). I also have MX303 (replaced with 304) heavy boot (below 20F/-7C). Both boots are very comfortable. Great for hike-a-bike sections. They are waterproof and windproof. I've had the 303 for many years and they are holding up great. I've only had the 146 a couple months, but they appear to have similar build quality. I expect they will last a long time too. When it comes to cycling boots, the flap that covers the front of the boot is a must-have. Other boots I've had leak melting snow and splashing water through the zipper or lace. Also, the cleat slots are sealed whereas other boots are not. These boots keep my feet dry in slushy snow and even when my foot breaks through the frozen creek. My normal shoe size is 45.5. The 303 fit best in size 46. The 146 fit best in size 47. This is with a normal weight sock not thin cycling sock or heavy wool sock. I don't need a heavy sock with either of these boots. They are warm enough with a normal midweight sock.

Shim required for cleats

I returned this product before using it
Size Bought:
6' 3"

According to a prominent warning on the shoe, you must use a shim with your cleats or you void the warranty. Therefore, you are not going to be able to ride your shoes immediately after they arrive unless you order some additional parts first.. The warning says that "Spring Binder Style" cleats, like Crankbrothers, Look, Time, and HT, "must use Shoe Shield or Shims that are provided by the pedal manufacturers. The Shields protect the shoe sole from friction and eventual sole breaking." I'm using Shimano SPD cleats (SM-SH51), therefore that doesn't apply to me, but the general install instructions say that you should install your cleats with a 0.,25-1mm gap between the cleat bottom and the sole bottom. I used some doubled up thin cardboard from a six pack of beer to make some roughly 0.5 mm thick shims. I looked around and Shimano makes some 1.0mm shims for my SPD cleats (part number YL8098030). You can see them on Shimano's website if you search for "SPD Cleat Spacer", and Shimano states "For SPD Cleats (SM-SH51/SM-SH56)". I ordered the spacers from amazon for $10, and when they arrive, I will replace my cardboard shims. Note that SPD cleats (as well as the Shimano spacers) have small teeth on the bottom that dig into the plastic sole of a cycling shoe, so my cardboard shims may not prevent the cleat from moving. Next, Lake says the cleat should also be 0.25mm - 1.0mm inset from the ground. With no shim, I measured from the cleat to the top of the lugs on the sole, and the cleat was inset about 1.5-2mm. I also measured the inset for the same cleats I use on my Specialized Recon 2.0 cycling shoes, and it is about the same 1.5-2mm, and I installed them with no shims. I'm a little worried that the Shimano 1.0mm shims may make the cleat extend too close to the top of the lugs, which will scratch the floors when I walk around inside. For comparison, I ordered the Lake MXZ304 Mountain Bike Shoe, which also requires a shim for your cleats and which I like better than the Lake MX146. Seem my review of the Lake MXZ304 Mountain Bike Shoe for sizing tips. The sizing of the Lake MX146 was somewhat similar to the MXZ304: the 48's were too small, and the 50 fit, but the size 50 in the MX146 felt too big and sloppy. Also, the elastic cuff around the top of the MX146 is loose and has gaps, so snow, rain, etc can get in. The cuff on the MXZ304 fits snugly, but I think you would have to employ some waterproof gaiters to really prevent stuff from getting in the top of the MXZ304, which has a ring on the toe for gaiters. I also don't think the MX146 will be warm enough for me, so I am going to return the MX146 and keep the MXZ304.
