Two pairs are mis matched as shown by the sole pic. We have a 43R and a 44L.
Next pair is a 44 but two different size 44's. They seem to match ok. Last pair is a 44R and a 44.5L. All pairs seem to fit like a size 10-10.5.
There's not too much difference in the shoes. One could definitely use an insole to fine tune the fit.
