Had my first pair of KSwiss Classics back in the 70's when i played a lot f tennis, and just liked the feel of them.  Got away from them for a while, but saw them on Amazon and ordered a pair.  They arrived quickly.  They fit well, I think that they are made so they are pretty much on standard when sizing.  Have had them for a few months and are wearing well.  I think the old ones froom my younger days had a little better quality of leather, but it is not that much of a negative.
