Had to exchange for a 43.5, and that size fits nicely. Haven’t used my G8 insoles because the arch support is pretty good as is. Have ridden several 26 - 30 mile rides and a metric. Would be nice if there were 2 BOAs, but it hasn’t been critical so far.Biggest issue seems to be that I cannot get the cleats far enough back. The center of my cleats end up somewhere under my metatarsal, but not behind by any impactful length. I ended up buying some Form baseplate extenders for my Speedplays.
