In reply to joe.91:
I found I could comfortably wear a half size down in the instinct - I think it's because the toebox feels wider. Neither are super downturned or asymmetric compared to other brands, but I suspect your feeling of support comes from larger than usual sizing? You'll need more foot compression to gain the same support in them I suppose.
Miura VS are more comfortable and similar if a little less downturn to Instinct, but slightly narrower tobox. Heel is tighter also. More comfortable as no toe rubber so the footbox has more room to go to on top and less pressure on knuckles.
