Sidi men's size 44 have been great for me for the past 10-15 years and have included road (genius and shot) and mtb (dominator x 2); however I was unable to get the fit on the size 44 frost to work for me. They seemed too large, especially at the heel, and using thicker socks and shoe inserts did not help. I tried the 43s and they were too small. My wife wears a 42 in Sidi road and mtb/gravel shoes and the 42 frosts fit her fine. She has used these for the past two winters and loves them -- so clearly they are a nice shoe. I just wish that Sidi had used the same last for the Frost 44 that they use on their other shoes. If they change the fit, I would definitely reconsider.
For some years now, I have been wearing an earlier version of this bike shoe with my tandem that has Shimano cleat pedals. I only needed them for about 3 months of the year, but they kept my feet cozy. Wearing these shoes is a lot easier than wearing multiple pairs of socks or wrestling with toe covers, and do a better job of keeping both your feet and ankles warm. Last year we got a second tandem, but use SPD pedals on it, so it was time to get the Sidi Frost MTB shoe. It works just as well as the earlier version. With Sidi Frost shoes for each tandem, I never have frozen feet in the winter.
I use it for cold weather riding in the Midwest. I like the wind proof gortex and the Boa ratchet system. Power transfer seems the best for any shoe I have ever used. Not super comfortable to walk in but feel super comfortable while pedaling.
I am a long time SIDI shoe wearer and currently have three other pairs of SIDI shoes (road, MTB). The SIDI Frost foot fit is fine but the fit at the ankle area is terrible and causes a lot of discomfort. I've tried different tension levels etc and hoped that after a few rides they would break in a bit, but no luck. Very disappointed. Would not recommend.
Gravel and wintry rides mostly, they are incredibly versatile when it comes to cold and wet. The fit of Sidi Frost MTB is different than the road version. I have both and use them all winter long, with proper wool socks they handle everything and all temperatures. Above 48 degrees I still use regular shoes and booties, but 48 and down to mid-20s its the Sidi frost for my rides.

I was not able to find a size that fit me. My normal cycling shoe is a Bontrager size 44. These 44's were a little too small and the 45's were way too big. I switched to the 45North Ragnaroks and those had the same fit as my Bontragers.
5 stars because they seem like if I could have found the right size they would have met my needs of keeping my feet warm and dry.
Use it for cold weather road and MTB.
