I have my cobbler take in the leather H upper closer to my ankle. On one pair he took in 1/4 inch on each side
i size up on the Oran or oasis bc I like extra length
37.5 boot; 38 Oran; 38.5 oasis
I am the same size in the extra as the chypre, and 38 is the right size for me in the extra. But someone, maybe
@Bdbunny ?, commented that the chypre sizing changed and now runs large (so size down). Apologies to
@Bdbunny if my recollection is faulty. In the all leather chypres from a few seasons ago, I was a 38. I tried on a shearling chore early this year and I was definitely a 37.5. If it helps, I am a 37 Birkenstock or dior act sandal.
ETA: the wide variation in sizes may have something to do with how your feet are shaped. If your feet do not conform to the shape of the H insole, then perhaps one sizes up (as i do).
