These are not specifically stated for wide calf. I took some photos of me modeling a pair (I decided to keep) and you’ll see how much room there is. Also, note there is an adjustable buckle in the back and where it is set at in my photos so you can gauge if they will work for you as a wide calf. I do have athletic calves my mid calf measures 14.25” for reference.
