I've been buying UA Elevated socks for years and these are the first ones I've found to be "baggy" and chunky on my feet - they fall with me the size 7 ft slightly larger. They were mostly fine until I put the shoes on. Due to the looseness, they slip between my heel and boot as I walk, causing friction and eventually calluses. Pulling up helps temporarily, but it lifts the heel a little outside of the shoe and eventually it just slides back into place. Who knows, maybe they fit people with big feet. Personally, I go back to the previous version with a tighter fit.
