I have a long history of riding in the coldest days in Minnesota winters; and I love my Wölvhammer ; but they are pricey and could be overkill for many riders.

I've used nylon platform with hiking boots; and Eggbeaters with MTB shoes with covers, and Wölvhammer. With standard cycling shoes and shoe covers, the heat sink issue can be a factor. However, with Wölvhammer boots I've never have an issue.

Also for the heat sink issue look at insulated insoles - Jaztronaut | 45NRTH

This was the Fatbike Frozen Forty, 47 miles of icy single-track took 6 hours with temps around -10F at the start.... warmed up to 10F by the end of the ride. The only time my feet were cold was at the end of the ride when I was standing around waiting for prizes - there was NO WAY I was leaving before they had the drawing for the CF fatbike frame (I didn't win it).

Sounds very similar to this: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

I put those in my SPD MTB shoes, and they don't do crap. Below 32°F my toes are still frozen after only 45 minutes or so.

IME - below freezing, I need a shoe covers for my MTB shoes. Most MTB shoes have venting for summer riding, so an insulated insole is only part of the winter solution. I like my Planet Bike Blitzen shoe covers for temps between 15F and 40F, especially for rides under an hour with a road bike (those 45NRTH boots are HEAVY!!)

I can't find any full insulated shoe covers large enough to fit my gargantuan US size 13 MTB shoes that don't cost more than the damn shoes themselves. I tried some last winter, but they didn't really help, and they ripped after just a few uses. I also had to perform extreme modification to the shoes themselves to make the covers fit (completely removed the plastic sole lugs underneath the heel area), and even after that, getting them on and off was a workout in and of itself, with me breaking a sweat just trying to get them on over the shoes.

Sorry, I got no suggestions for giant feet. Even with my 10-1/2 feet, shoe covers aren't easy to work with, and I have XL covers for less than large shoes.

But you know what they say about guys with big feet.... they need big shoes.

I also had a very had time finding large shoe covers an ended up with these. The size and price are both good. I use them with very good insoles, wool sox an hot shot heat packets for very cold days. It's ok but cold feet are a problem when it gets below zero f.
