Costco has the Khombu leather winter boots on sale for $29. You can also find these online along with other winter boot varieties ( https://amzn.to/2JcV7OS ) I owned Khombu boots and found they last a long time. See my comparison video here:
I compare my Khombu waterproof leather Summit Hiking boots with my Flume winter Hiking boots from 4 years ago! Summit was also found on Amazon for about $59+ : http://amzn.to/2BPPYc7 Full review, the new Summit is more comfortable compared to the Flume model, with the memory foam insert, but still lacks arch support, The boot is rated at -20 degrees vs -40 from the Flume model. This makes Summit more usable year round.
