This product page isn't clear about the width of the calf.  I would recommend looking elsewhere online to find measurements and read about different experiences as there aren't many reviews here.  However, on many other sites selling these it states, "Wide calf circumference accommodate pants and a variety of calf sizes."  This just isn't true.  It's a very narrow boot from foot to calf.

Here is what I found:

- Heel Height: 1 in
- Shaft: 13 or 14 in
- Circumference: 15 1'/2 in.
- Weight: 2 lbs 1 oz

If you require a wider calf size, this boot is not for you.  I heard this boot compared to the Hunter boot but I found the Hunter boot wider on the calf.

And just to be clear... the laces do not mean you can loosen the boot.  You can only make it tighter with those laces and only at the top of the shaft.  They are not "real" laces.  There is an inside lining that determines what the shaft size is under the laces and this is not flexible at all.  The laces are just there for show over the actual boot shaft.  Cosmetic and not much function.

Sizes are also whole.  I am an 8 1/2 and ordered a size 9 and it wasn't too big in this regard. But it is very, very narrow. Mostly it's the calf size and misleading laces I have a problem with.

It is otherwise a very nice looking boot and you'll probably be very happy with them if you don't have sizing issues.  Luckily, returning them was painless.
