The Sidi Frost Gore Winter MTB Shoe is designed for lightweight, reliable protection from the winter elements with this ankle-height mountain bike shoe. Featuring a lightweight Microfibra Microtech upper, the Frost Gore shoe emphasizes elemental resistance, stability, and comfort without sacrificing on weight or performance. Doubling down on this, Sidi utilizes Gore's iconic Gore-Tex membrane to keep water out, yet allow steamy water vapor to escape easily.

Delivering that perfect fit Sidi is known for, their Techno-3 closure offers the same reliability and adjustability that has put Sidi on the map. This fully replaceable cable-dial system allows for a non-binding, on-the-fly adjustments for getting a glove-like fit. The new RS17 sole is lighter than the previous sole and has been upgraded with a more aggressive tread pattern, a replaceable toe insert and is toe spike compatible. This sole offers the optimal amount of stiffness for a stable pedaling experience, and features replaceable toe inserts and compatibility with spikes.

The Sidi Frost Gore Winter MTB Shoe is compatible with 2-bolt MTB-style cleats and pedals. Not available in half sizes. Claimed weight: 880 grams.

Other shoes out there are better at absolute cold, great waterproofing and high quality.

I've been running a set of Pearl Izumi Barrier GTX for the last 8 years or so and they have done an admirable job however, they lack proper waterproofing. These are WAY better in that regard at the cost of some lower temp handling, these aren't super insulated... The small laces dig in if going super tight as well. As with other SIDI products, the quality is top notch.

Garbage quality

If you're expecting these to be as well made as Sidis normally are, you're going to be in for a surprise. These are terrible quality shoes. After two eight mile rides the exterior part of the shoes wore out and exposed the Gore-tex liner, which is terrible material quality on so expensive of shoe - you shouldn't see materials wearing out that until they've been ridden for years.

Great fit and comfortable

I have Sidi summer shoes and I like the quality

and fit. I went with size 44 like my summer shoes and they fit perfectly. I havent done a ride in very cold weather yet to find out how worm they are.

Great service and price from Bike Tires as usual.

Definitely an improvement over shoe covers!

These shoes are great for winter riding. My feet are warm and toasty for temps in the lower 40's down to the lower 30's. My only complaint is the fit is not quite as perfect in the heel cup as my other SIDI shoes. It may be that they allow for a heaver sock. It's a small complaint as the fit is decent. At the price I was able to get, these shoes are worth the money!

Great shoe - usual Sidi quality throughout

Bought these for winter riding as my older Shimano MW81 winter shoes were starting to wear out. The Sidi shoes are lighter and way easier to get on and off than the Shimano shoes. So far have used them down to about 20 degrees with toe covers and no problems with staying warm. The only drawback is that the cuff does not fit as tight as I would like, and snow or rain can get into the top of the shoe. Otherwise they have the great overall Sidi quality.

Warm, comfortable & Good Looking.

I have regular Sidi riding shoes and love them. When it turned cold enough that I could feel the wind coming through the vents, I realized I had to find a solution. I tried those booties that go over your shoes and they work okay, but are a complete pain to put on. And after one wearing that was mostly riding and very little walking, I had almost worn a hole in the bottom. So I paid quite a lot for these shoes - and worth every penny. They are easy to put on and take off. They are warm and very comfortable to ride with. They look great too. I wear a perfect size 10 and a half. My summer Sidis are 45s, and so are these. They fit perfectly. Use the Sidi size chart.

A racer's shoe

The good, it's a racer's shoe first and foremost. Very stiff platform to put the power into the pedal. The shoe is slim and light, yet still keeps the elements out. 20 degrees is the lowest I've had to ride in, but with medium weight socks the feet remained happy. Good materials and construction throughout. And the bright green strips will make you go faster.

The bad, I'm on fence giving recommendations for commuters. The shoe is waterproof, but the ankle strap leaves a gap. If your pants don't cover the top of the shoe water will get in and since it is waterproof it's not going anywhere. Gators or long pants are a must if riding in rain. Because the ankle cuff is loose walking is not a problem and the sole has a softer plastic so at least you won't sound like a shod horse when walking indoors.

The ugly, the price for one, you'll need to hide the credit card statement from you know who and the fit. They said to order up a size. Makes sense if you'll be wearing a thick winter sock. But the sizing seems spot-on, so anything other than a thick sock seems too loose. It is a winter shoe though and some of you wear two pairs of socks, if you're a racer you might want to get your actual size, assuming you'll use a single middle to light-weight sock.

Excellent, expensive shoes that run true to size.

I have nothing but good things to say about these shoes, except the price which of course is flat out expensive. If you can get over that they are a very good choice in winter riding shoes. Why I am taking the time to write a review is to help with choice of size. I wear a 10 D US shoe size. I have never fit into a 10, and I rarely wear 11 except when the shoe only comes in whole sizes. Depending on which chart you look you look at, a 10 is either a Euro 44 or 45. On the Sidi chart on this site, it is a 45. I have Sidi summer weight riding shoes and read advice from more than one source advising going one or two sizes higher because they run small. 45 was perfect. I love those shoes, so when I started shopping for winter shoes I went looking for Sidi, only to be advised the same thing they run small. Since I had Sidi shoes already, I decided to ignore the advice and order 45s. Perfect fit, it turns out. I can't speak for other sizes, or odd shaped feet, but if you are pretty sure of your own usual size, my advice is to order according to Sidi's size chart.

Comfortable and Protective

These shoes are very comfortable and provide top protection form wet conditions and colder weather. The fastening system keeps the foot stable while pedaling. Walking in these shoes is near natural.

Excellent

I've worn only SIDI's for the last 30 years or so. Sold on them.This is my first winter boot. I live in Colorado and ride these in wet, muddy snow in the 20 -30 degree range and with the heavy wool socks I wear, my feet stay comfy and dry, no bootie needed. Well worth the price. Only wish it was an SRS model. I replace the treads often on my other SIDI's.
