Would buy again but... - Sorel Joan of Arctic Shearling Winter Boot - Women's

I bought these to replace a pair of wore out The North Face. Normal shoe/boot size 7.5 ordered an 8 to fit medium weight smartwool socks. Fit well. They are a bit big looking but I like them. I do not believe they work for -25 temperatures. We ride snowmobiles in varying temp ranges. Last night it was 4 degrees my feet were fine when tucked up getting heat from motor but if we were stopped and standing they were very cold. I do not double socks and I have room in boots also so it isn’t that they are too tight. I think they would be fine for less hours outside or a bit warmer temps. Time outside 8 hours.
