I first acquired the model brown nubuck in 41.5 (I put on the 42 normally). No problem: as in slippers from day one, comfort and lightness, the elegant look and more. So I fell for the black leather model. Even finding, except that comfort is a stiffer hair, the leather should be done, count 2 to 3 days. This is a great shoe, well finished and comfortable but will not suit all forms of feet (narrower than Doc Martens Sawyer for example). So far no big sweating problem, the Gortex lining seems to do its job properly. In short, a model to test absolutely recommend but before the acquisition. Quality / good price especially during promos.
