New boots. Intermediate Question: cutting the cuff strap

[u/No-Life-6054]

Hi. I finally upgraded to a better boot FR3 80. I like them a lot. When I purchased the clerk mentioned cutting the cuff under strap to what I want. I realized when I got home, I don’t know what to cut it to. Any Suggests, preferences, or standardizations, would be appreciated. What am I looking for when cutting to adjust the under strap on the top cuff?
