How to Measure Your Foot

  • Place your feet flat on a piece of paper and mark your longest toe and the back of your foot. It's best to do this standing and wearing socks
  • Measure the length (cm) straight from your longest toe to the back of your foot using a ruler or measuring tape.
  • Use the chart to find your size.

Rated 3 out of 5 by from Need serious winter boot Super warm and dry. Yet, way too small; especially with wool socks! Order full size larger than your norm.

Rated 5 out of 5 by from Montana weather, lookout This boot is warm and is insulated. It’s been great for posthole-ing through the snow drifts on family property to feed horses and to hike up a few ravines for a better view of the river below. Next will be using them for snowmobiling.

Rated 1 out of 5 by from NOT WATERPROOF They were great until my husband wore them outside. These "extreme snow boots" will leave your feet COLD and WET. Paid $150 for this boot rated for -60 F. I'd hate to wear them in anything less than 30 F and sunny with no snow or rain. They suck.

Rated 3 out of 5 by from Had to return Things I liked- Boot was tall and kept snow out. I would guess would be very warm in cold conditions but have not tested. Things I didn't like- Too warm for me personally, because my foot would get to hot walking for periods of time in temps above 20 degrees. Drawstring on ankle broke on first pull and doesn't get tight enough. My ankle slid even with inserts and wool socks. I tried a size down but that was too small. All in all- These boots would be great in my opinion if you used your own laces instead of the drawstring, which is easy to do. They would also be great in temps at least colder than 20 degrees if you plan on walking a lot.

Rated 2 out of 5 by from Sorely alpha pac xt These boots are rated for -60. I toured around different stores and these had the lowest rating I could find anywhere. I needed them for work in a hurry, and the shoe salesman assured me they were the warmest I could get. My feet need foot warmers at 20°F with these and at the end of the day my liners and heavy wool socks are wet and there is water in the rubber footbed area. These need a footbed support to prevent sore feet.

Rated 5 out of 5 by from Excellent winter boot This is a very warm boot even without wool socks. It is light weight and easy to walk in. The quick cinching laces and straps are a nice touch. My only complaint is that the tabs on the upper straps are too small - they hide in the buckle so they are very difficult to grab onto with bare hands. I would also add a little more padding in the insole if you are standing for extended periods.

Rated 5 out of 5 by from Excellent boot for what it's designed for This boot is perfect for the harsh, snowy, unpredictable weather of the northeast. They are warm, and comfortable. I use them for snow blowing and enjoying time outdoors. They are big and clunky but so warm and toasty. These are not designed to win fashion shows or hit the bars, they are designed to keep your feet dry and warm in harsh conditions. If that it what you are looking for, then this is the boot for you.

Rated 2 out of 5 by from not -60F Where do they get the temperature rating from? My feet were slightly cold at 15F degrees definitely wouldn't have been comfortable at -60 as they are rated. Also the drawstring system doesn't draw snugly so you wouldn't want to do much walking in these.

Rated 3 out of 5 by from too large/no ankle support i am a size 9 in mens. i ordered a size 9 despite the reviews of the boot being larger than average. i thought i could wear heavy wool socks with the boots well the boot was about 2 sizes larger. with 3 pairs of socks on it was still a little loose. and i was walking around. i didnt have much ankle support, maybe because the boots were too large. the boots felt comfortable, bulit to last. returned due to size and i got the wool CARIBOU boots inplace and love them! i got a size 8 and they fit awesome.

Rated 5 out of 5 by from I little too big Purchased these boots in size 11 since I tend to wear either and 11 or 11.5 in sneakers. However these are too big and my foot moves around a lot. Can't even return them since I hair saw they don't have a size 10

Rated 5 out of 5 by from Best Boot Ever Hi, I got a pair of these boots back in 2008 while living in Steamboat Springs, Colorado. They are comfortable and very warm. I use them in deep snow and also while snowmobiling and have never been cold it is not 2015 and i have yet to have any issues with the same pair. While they are not the cheapest boot in the world figure the price over 7 years when buying them its worth it.

Rated 5 out of 5 by from Alpha Pac XT I snowmobile in Northern Wisconsin and the UP of Michigan where at times, temps can reach -30. I've had this boot for 10 years or better, and just ordered replacement liners. The one thing I like over other Soral boot styles is, they have an elastic draw string to tighten rather than a shoe lace that could come untied and get caught in moving parts. They are easy on/ off and the liners can be removed to dry out.

Rated 4 out of 5 by from Good Boot Overall, the boot is very nice, just like all the Sorels I have purchased are. Fit great, very comfortable and feel rugged and durable and dependable. The only issue I had was on the third time of wearing them, I pulled the right boot draw string and before it began to get even snug, the pull cord broke. I had not been out in rough terrain or doing any work where the environment could have slightly cut or compromised the pull cord, just a few times around the house as we had a break in the weather and it was to warm to wear them. Outside of the pull cord breaking, it is a great boot...I will put a heavier cord in both boots to replace the originals. I do recommend this boot.
