After 10.5 winters, my beloved boots needed replacement. I tried to find same pair/style, tono avail. My Columbia boots are 8.5 in woman's size. After researching and seeing reviews in a winter FB group I'm in, many recommended this brand. The price to be honest, was high. My Columbia pair was less than $85 USD, so I was hesitant to spend over 100. Reviews mentioned ordering "youth" size. I did (figuring I could return free, if to small or save for my 10 year old)WOW these are huge! Obviously only way I'll know for sure is this upcoming winter. They are not as stiff/solid feeling in the ankle area, as my Columbia boots(I have a plate and 6 screws) so that does worry me, I don't want to have my ankle give out. I do like the feel of them and the inner lining.The youth size was/is significantly cheaper than the adult sizes. As you can see in the pictures, they are much larger than the competition, even though they are labeled a smaller size. I wore them in the house and around the yard, very warm inside, which I loved. I hope these last 10 years +
