OK thx fellas... sorry to derail with the f'g size questions but I truly searched for posts with similar measurements. The 43 and 10 conversion seems correct so I should be alright.
I know.... the device! But when the cut is different and I'm not familiar with the shoes I don't know how much it helps. I've practically given up on labeled sizes.... bought a kash sweater the other day in "L"... I don't wear large anything!! and the sandals I bought a few months ago were 8.5... haven't worn that size since elementary/ jr. high times... go figure.
