Mens Solution sizing

Any one have a size comparison between the solution and the Miura or Miura vs. I wear a size 39.5 Miura lace and a size 40.5 Miura VS wondering what size Solution to order while there on sale. No store near me has the solution in stock.

I climb in the solutions and the muira vs' and I wear the same size in both. My first pair of solutions I bought a half size too big and once they broke in they didn't perform nearly as well.

I wear a 43 in the Miura, after a resole or a few hours in them on a warm day they get a little stretched out. I wear a 42.5 in the Solution and find that they're the correct size, uncomfortable until break in and then the kind of shoe to take off after a send. Next pair of Miuras will probably be 42.5s.
