Slow break in period, but my go to boot afterwards!
These boots kept my toes toasty warm as I cleaned horse shelters in the winter and were great for hiking in the winter as well! It took me a while to break them in because of the laces, but once the leather softened up I was able to wear them all day with no issues. I've finally worn out the upper section on the side of my foot where it flexes the most, but as long as I don't step in a puddle or deep snow they'll keep my feet warm until my new ones arrive.

Best work boots ever.
I've been working and wearing work boots for over 52 years. These are the absolute best pair that I have ever worn. The fit is great. Available in a medium which is hard to come by. Great attention to detail. They were all covered. Nice roomy toe box. The size 9 1/2 that was recommended through the third party was a little roomy. The sample shoes that I used as a size comparison are casual shoes and I like my work boots a little snug so the sizing was very accurate. I purchased a pair of 9 M for my next pair
