Since getting my Blackstones a few years back, I have been totally converted to shearling-lined shoes for winter. I would like a pair of pull-on boots that are completely shearling-lined. Some of the Uggs styles I like (the ones that tend to look more sneaker-y) I can see from photos on Nordstrom & Zappos don't have a lined footbed—only the uppers. Is this true for all Uggs? I thought Uggs lined the whole inside with shearling. Any insight is welcome! Thank you in advance!
