I have Hyper Vs but I think I’m going to switch to the Avancus for bench. My logic is I’m 6’3” and the thickness of the sole on the hyper vs effectively lowers the bench height. I think there might be some benefit to being closer to the ground and “shortening the tibias”.
I had the same thing with the 43 v the 42. I wear a US size 10 in regular shoes as well. With the soles in a 43 is perfect but without insoles I had a bit of room that me foot would slide a bit. Then sized down to 42 and it fits perfect
