I often have that problem with various brands— need a “ quarter-size” up! Sometimes in the larger size I just lose something in the overall look of the shoe on my foot and leg. Or the heel not only slips but gaps.
I DO gravitate toward suede footwear
for that reason- I can’t undersize, of course, but the leather is just more giving and forgiving overall. Similar would be true for a very buttery smooth leather.
I would also be sure the actual some us not too narrow— needs to support your foot. I would try them at home, and with different hosiery, to see if you can decide.
I recently got the shoes below, in smoothleather, and was worried about in- between fit , but the 1/2 size up was just too much. I kept the smaller size
and it worked great. But I didn’t know for sure until after wearing a few times!
