Boot Cuffs: Skinny Calf Solution?

 focusing less on this type of legwear and more on various other apparel & accessories

Gotta cop to watching some daytime TV today. Well, listening anyway -- I often have something fluffy turned on while conquering multiple loads of laundry and doing more mundane editorial tasks. Today I actually hopped over to the screen during a Shark-Tank-focused edition of "The View" to see if the boot cuffs sold by a company called Grace and Lace might help "close the gap" for us thin-calved boot lovers.

The legwarmer solution has been known for a while in skinny calf circles, but come spring weather, legwarmers might warm the legs a bit more than we really want. Same problem, but worse, for "boot socks" (how these differ from regular long socks I'm still not sure, but apparently they're a thing...). These boot cuffs, though, could be handy. You extend your calf circumference a little to narrow the leg/boot gap up top without adding unnecessary heat or bulk elsewhere.

So what do you think? Would these work? Are they cute? Too trendy? Worth a shot at sale price? And most important, with this company selling like gangbusters, why didn't we think of this idea?! :} Do share your thoughts in Comments...

Fall 2016 update: Steve Madden has gotten into the game too, with a cute line of cable-knit and lace-topped boot cuffs priced at under $20 each. Not sure how many department stores carry them, but check your favorite shoe sources online.
