Tony Bianco leather boots question

Hi everyone!

Just wondering if anyone has any insight on Tony Bianco boots. I bought the dusty boots as they are on sale, they fit beautifully everywhere except around my calf at the opening. They zip up and aren’t uncomfortably tight, but I have pretty big calves compared to the rest of my body so when the boots are zipped up I have a leg muffin top lmao. Not super noticeable from the front but definitely noticeable from the side.

If anyone knows from experience how much they are likely to stretch/mould around my leg, if it’s worth getting leather softener, or think it’s best I return them before I become emotionally attached, please let me know!

The boots are for work and I usually wear a suit / pants so it’s really only an aesthetic problem that I will be aware of, but thought it was worth asking anyway!

Thanks in advance xxoxox
