Lejan shoes rubbing Achilles tendon

I recently got a pair of Lejan Ones. I like the way they look, and they’re quite roomy (roomier than expected). However, the right shoe just keeps rubbing my Achilles tendon so much so that it causes bleeding unless I use a silicone patch. I suspect it’s because my right foot is slightly smaller, and I have narrow feet in general so the shoes move as I walk.

Do you have any other tips that would help?
