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.
