Addressing top of toe friction in Solovair derbies

I’ve had a long and fraught relationship with my Solovair Greasy Grain Gibsons since I got them in the early Summer, particularly with breaking them in. Although they initially were wrecking my heels and the sides of my pinky toes, after using a shoe stretcher and wearing them at the office as often as possible, I’ve gotten them broken in to the point where they are comfortable with the exception of one spot (on both feet)- the top of my pinky toe (essentially just above the cuticle for the toenail) is getting a lot of friction as I walk and over time it causes blisters. Is there a way to address this pressure point and either loosen it or stretch it? My shoe stretcher doesn’t seem designed to stretch the top of the shoe (it has bunion plugs but those are for the sides, and it has a pad to raise the vamp but that seems like it’s too far back to be the issue)? Or is it just an inherent issue with the last? I’m trying to avoid giving up on these shoes because they’re so beautiful, but I can’t walk more than 30 minutes in them without dealing with the consequences! Thanks 🙏
