If I may chime in, I bought a 7.5 UK in the brown suede tassel loafer on the Ron last and found it way too roomy. I have several other pairs in 7.5 UK in the Hiro last and they fit me perfectly straight away and get better with each wear. I'm a little annoyed because I asked Pepe before ordering the loafers if I should take the same size in the Ron last and he said yes. My experience tells differently. I tried to make the loafer work by having a good local cobbler remove the Meermin insole and replace it with an insert, but they just don't work. In fact, if anyone is interested in them, give me a holler. Aside from the insoles having been removed, they are pristine.
