I already have unlined bullhide triple-sole mocs, lined bullhide triple-sole mocs, and lined buffalo hide triple-sole mocs. Wow on the buffalo hide BTW. lived in Green Bay for 6 years and these shearling slippers are perfect for extended winters. But I’ve just arrived in Vancouver, Washington where it rarely snows and heating needs are less. These slippers are nothing but an indulgence. Not sending them back. They are fantastic and they fit my wide Fred Flintstone feet, something Ugg slippers are weirdly incapable of manufacturing. Next up is a pair of canoe moc boots. Keep making them, guys. I’ll keep buying them.
