Technical features keep your feet toasty warm
Tomorrow is the vernal (aka spring) equinox marking the beginning of spring, but outside my window, it’s sleeting. There’s still snow on the ground in the north, and the fat bikers are riding. As I wrap up the last few cold-weather riding gear reviews, I would be remised not to include Garneau’s new Klondike M4 winter boot.
Adjustments are easy with the BOA M4 IP-1S closure system with specific left and right-foot closing mechanisms that tighten easily even with winter gloves. The Velcro ankle strap is also glove-friendly and helps provide a snug fit.
These boots kept my feet warm and dry because of the 300-g Thinsulate lining, which was company tested at -20 degrees C/ 4 degrees F. Personally, I tested the boots down to the low 20’s F riding and 11 degrees F shoveling the driveway. The 4-layer inner sole is made from 100% wool, polyethylene, Metal Heat, and EVA foam to also keep your feet warm and comfortable.
The Klondike M4s run small, especially if you want to wear winter socks. I requested a size 45EU from the company since that is what I usually wear for Garneau shoes. But the boot ran small, with no half sizes, so I requested a 46. The larger size fit fine but still was snug when wearing heavier wool or alpaca socks. I did notice the foam compacted some after the first ride, reducing the volume inside the boot. The company’s marketing materials mentioned the boots were designed for riders with wider feet. I wear a B and found it a little roomie on the sides, even when cinching up the BOA laces to take up some of the volume.
The outer sole is made from VIBRAM® DURATREK for a stiff sole which equates to good power transfer. I don’t clip in on snowy and icy fat bike rides, and the soles of the Klondike M4 gripped the flat pedals nicely. Also, when getting off the bike, it was easy to walk in these boots—even with the above ankle design. They weren’t clunky like some other brands of winter riding boots and lighter at 609g per boot (weighted on my gram scale).
Some additional features include reflective piping up the front and back of each boot and a reflective logo. Being visible in low light conditions on three sides provides an added layer of safety. There’s also a loop to hook a gaiter if the snow is deep.
At $351, these boots are pricey, but they are in line with other quality winter boots. If you’re a winter rider and out on your fat bike in all kinds of winter weather, you want to be prepared. Cold feet are not fun and tend to shorten the ride. Because the Klondike M4 is lightweight, warm, and “walkable,” they can be used for snowshoeing, too.
