Creasing by toe on wholecut AE chukkas

Hi All, just wore these for the first time yesterday and noticed heavy creasing (with some accompanying blistering) just under the big toenail of my left foot around where the toe cap would be. Strangely, my left foot is bigger so I would have thought creasing would occur on the right if anywhere.

I have other AEs in the same last and size (with no fit/creasing issues) so I'm wondering if this looks normal. On the right shoe it seems the leather is too stiff near the top to crease there.

Any thoughts? Thanks a lot.
