Description

Ignore the winter.

Depending on the degree of your addiction to singletrack, cabin fever can start creeping in shortly after the snow's fallen and the trails are covered. Whether you just have to bust out of the house and go get lost out there, or if you never yield to Mother Nature to begin with, the Diadora Polarex Plus Mountain Bike Shoes are your best friend when it comes to getting out on the trails this winter.

The upper of the Polarex Plus shoes is made of element-proof Suprell-Tech. It's a material that's as tough against abrasion and impact as it is resistant to wind, snow, rain, mud, or whatever else you encounter out there. Inside, the shoes are lined with Diadora's Diatex waterproof membrane, further keeping out the nasty stuff. Inside of that is a soft thermal lining that insulates further, and it's also very soft and comfortable. The sole is aggressively lugged, and based on Diadora's Performance MTB CR sole, with a stiffness index of 6.0 on a scale of 1-10. The engineers could have made is stiffer, but for walking off the bike on slippery surfaces, a little bit of flex is necessary for stable footing. The shoes' fit profile is Diadora's Race Plus, which is snug but not constrictive, allowing you to wear thick socks if you'd like, and the entire system laces up with a Boa closure system, making it very easy to dial in a comfortable fit every time you put them on, even while wearing gloves. And at 395 grams for a size 42, these things are incredibly light for how much protection they afford.

comfortable, warm but broken

  • Familiarity: I've put it through the wringer

When I received these shoes and tried them on, I instantly liked them. They were very comfortable and roomy enough for extra socks. I found they kept my feet warm when the temp dropped to around 35F with regular socks and around 30F with extra wool socks on. However, after only 2 months of use, the Boa lacing dial broke off. I was a couple miles in on a local trail at the time. Fortunately I had tape on hand and was able to tape the dial down and keep going. Once I saw how the Boa dial is held on, I am not surprised that it broke. The shoes are under warranty so I might give them another try, provided my size is available.

Great Cold Weather/Commuter Option

I ride 5 days a week and this has been my go to shoe since the weather turned cold this year. So far, my commuting temperatures have ranged from 30 to 50 and, with good socks, I’ve been comfortable on every ride. I do plan to ride with overshoes once temperatures retreat below 30 degrees. I haven’t ridden with these shoes in the rain yet so I can’t comment on wet performance.

Initially, I found the fit to be uncomfortable - this was driven by overtightening the Velcro around the ankle. This was causing shoe rub and the problem was solved by simply allowing the Velcro top strap to be loosely affixed. I have had no issues with discomfort since changing my approach. I typically wear a 9.5 shoe and found that size 43 was sized appropriately but wearing two pairs of socks would probably drive me to a bigger size... I’ll just use overshoes instead.

I’d confidently recommend these if you’re looking for a trim, not bulky cold weather option.

Use for commuting and winter training...

I love Diadora shoes. I have a high volume foot, with evolution toe to boot, and Diadora shoes seem to fit me better than any other manufacturer out there. I normally wear a 45.5, but had to get these in 45 since it seems the entire world was out of them in 46. That said, even with good wool socks on, these are still slightly roomy. Performance... Well, that's where I have issues. Wet weather performance for me has been less than stellar so far. Granted, the two times I've used these in the rain, it's been a virtual downpour. The neoprene gaskets hold water pretty well, and once they get saturated, you get wet feet. I also just used these on a long ride today (12/9/17) in temps that, with the significant windchill, were down into the 20s. I had on a wool sock under these and my toes FROZE. Again, this may be a bit of an extreme test, but there you have it. That said, in temps above 30F, they keep my feet perfectly warm. I've had no problems with the cold on those days I've commuted with temps that have been in the 30s. I'm going to get a pair of shoe covers for these and see if performance improves. I hope that turns out to be the case.

Toasty warm

I have only worn these a few times since our winter weather has temporarily crapped out on us here in Utah. I was able to use them in the mid-20's and during some rain storms too. So far I really like them. I appreciate the quick closure with the BOA system and they have been very comfortable.

Good winter shoe

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Used a few times down to low 20s. Feet were warm with two pairs of socks (thin thermolite + wool) and no chemical warmers. Run true to sizing chart -- larger than Shimano's for the same size. I wear non-insulated Shimano's in 45 and got these in 45 as well but they are 1/2-1 size larger (which was the intention to wear thicker/multiple socks). Boa works well. Wish ankle gaiter was a bit higher. No experience with these in the rain but feet stay dry in wheel spray.

Nice cold weather shoes.

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

I've worn these a few times in temps in the low 40s and they've kept my feet warm and dry. I haven't worn them in colder weather yet but I bought them a little large to be able to wear thick socks with them.
