Anybody riden with Lake MX140's or CX140's? I'm wondering how they compare to Lake's heavier winter shoe like the CXZ302 warmth wise. I have an older pair of Lake winter shoes but they are not compatible with SPD cleats and I recently upgraded to SPD pedals.

I commute year round here along the Colorado front range. I'll ride if the morning temp is at/above 20°F when I wake up in the morning and the snow ain't too deep or the ice too rutted. My commute takes about 1 hr 40 min when I have the studs on.

I have no experience with Lake shoes, Heard of them, Dreamt of them, Drooled over them. Lived without them. Survived just fine.
BTW, I rode all winter here in western Maine, the coldest I have willingly ridden is around zero F.

I have the MXZ302s and love 'em. Can't say about the 140s, but like you, I'm curious about them.

I'm tempted to think that a pair of MX140's about three sizes over with big thick wool socks under them might be warmer than most winter cycling shoes. At last someone has gotten the message that the winter cycling boot needs to be breathable to keep your foot it's warmest. Most cycling shoes use neoprene as the insulator. This is good for wet conditions but not for below freezing conditions as the neoprene does not breath well enough so your feet get cold from their own trapped moisture.

The MX140's do have a neoprene ankle wrap which is good. But the lower upper is lined with eVent which is a breathable membrane (about the best).

This really looks like an interesting winter shoe. And the price is not so bad. There is also a MX240 winter model about 90 bucks more. I wonder what the difference is. So now Lake seems to have 3 winter models.

It looks like the MX240 is made similar to the MX140 but it may have some additional insulation or something.

EDIT: The MX240 seems to have a carbon sole. This will make the shoe stiffer and should make it warmer too since carbon fiber is a better insulator than typical boot rubber and plastic.

Last fall I bought a pair of Pearl Izumi Barrier GTX.
They have Goretex for waterproofing, and a layer of insulation.
They were *great* for winter riding.
They were also great when I climbed Mt Evans a couple weeks ago and got caught in the rain on the way down.

I have the 302's.

I have ridden them down to -15F and been comfortable. They are heavy, but comfortable. My ride is about an hour in the winter. I use SPD's all year.

For a 20 degree ride, you should be able to get by with a lighter shoe. You can always add shoe covers. I used to ride my summer shoes (kind of like a hiking shoe) with heavy socks and shoe covers down to about 5F.
