u/BreadfruitParty2700

I just got my first pair. I got the 5400 last which is what's recommended, but there's tons of gapping between the tongue and the eyelets. It's really disappointing and I don't know what to do. I am a fat person and therefore obviously have thicker calves and feet. The boot itself fits, but it won't lace up right. Anyone else experience this and/or have any advice? I love them and I really don't want to return them.
