I think you're just having trouble seeing detail in the Saks pictures. The shoes are identical, including the heels and soles. However, the Saks listing describes them as having a rubber sole, while it appears to me that the sole is leather. Someone else (Joe?) may be more intimately familiar with this shoe.
I disagree with this assessment. The loafer in the Saks picture seems to have a molded rubber sole, similar to what you might see on a Prada Sport or a Cole Haan loafer, while the Neimans picture seems to have the more traditional sole.
They'll certainly work for the latter. As for the former, there are those amongst us who dismiss the loafers-and-jeans combo as being too "Euro-trash," but I'm not one of them. I think these would look fine with a pair of good jeans, especially if you go for the brown instead of the black.
This one one of those rare occasions where I'll have to disagree with pstoller. I just think that slim loafers just don't look good contrasted against the weight and volume of jeans, unless the jeans are very slim - and jeans that are too tight are, to my prejudiced eye - the calling card of Eurotrash (although recently, a great number of Eurotrash seem to have adapted a vamped up version of the skater-boi look. Old school Eurotrash, especially those from Eastern Europe and Germans, still stick with the old stawart.) If you must, get the Saks version. At least the molded sole will give it a sportier look. I've harped on this enough. I promise - no more rants about Eurotrash are forthcoming.
