I'm riding with the MXZ 304 boot for a year now and I wished I ordered them earlier. My feet stay dry and warm, even with temperatures below zero! A must have for the winter. I ordered one size bigger then my other lake schoes!
Warm boot but the sizing is off compared to other Lake shoes. They run at least a size smaller. Also, it's time to say goodbye to the Boa system for anything above the ankle. They stay tight for a few minutes and then loosen up completely. Useless system. At least there is a forefoot velcro strap to hold things together lower down. Please go back to straps and buckles!
I live in Idaho so winters are long. I needed a shoe which wasn’t as heavy or insulating as a 45nrth boot. This shoe fits the spot BUT size up. 1-1.5 bigger. Im a 44.5 and ordered a 45 regular and cant even fit a toe warmer. So size up and widen up for wool socks. I used it 20-25 degrees and it did well. Just had to use a normal sock so after an hour the toes started to suffer. I might try using a turkey bag but i still need so size up for max comfort. Besides running small… its a perfect shoe for 20-30 degrees. Lower than 20 will require your favorite trick for keeping you warm. Mine is wool socks and turkey bags.
The 304's are pretty good, and warmer than my Scarpa approach/hiking boots that I would otherwise wear. I can ride in the 304's for 2 hours in 25F temperatures - but my feet are getting cold towards the end of two hours. I did need to order up 3 sizes larger than normal (I normally wear a 47 and had to get a 50 wide). The Boa system works, but feels flimsy and I'm afraid it will break. I had a similar dial system on my Sidi Dragon 5's, but it seemed sturdier - and was easier to use. The 304 boots are SUPER tight to put on (like putting on a ski boot for the first time of the season), but once you are in, they feel fine. Getting them off is a chore, as the Boa system does not loosen very well. The thermal reflective insole is great - I just wish it was twice as thick for more heat retention. As far as an update, I'd get rid of the provisions on the sole for clipless pedal cleats - those are going out of style as most of us have migrated to platform pedals. I had to purchase the Syksol cover pads for the cleat area. The Vibram sole tread is very deep and picks up rocks and snow - I bet most of us purchasing the 304' are not racing in these boots and would prefer a less aggressive sole. I'd love to see a lithium-ion powered electric-heated insole option, and/or an optional neoprene toe cover for temps 25F and below.
The quality and fit is absolutely perfect. Highly impressed by this boot. I am normally a size 43 Wide in Lake MX shoes but am a size 44 Wide in the MXZ 304 boot (with thick socks). Five stars for sure!
