Any ideas for altering

I bought the Boogie - Black boots recently and they are just a bit too small for my calves to zip them up😭💔 I’ve literally wanted these boots for soo long since I saw them, and was wondering if anybody in this subreddit has experience make the boots to fit calves?! I’ve heard of sewing a calve extender to the boot but wouldn’t that make the zipper not be snug for the weight of the heel? The item specs aren’t available on their website anymore so I can’t tell you the weight but it’s basically a 4inch platform with the 6 inch heel. I bought them on sale so I cannot return them per their return policy.
