George,
Those are the same Korkers
Konvertibles that I bought earlier. You're right - just stamp down on them to seat the soles. Yours should have come with a rubber lug sole and a felt sole, but perhaps the close-out pair you got didn't come with felt. You can buy extra soles for this model. I've used both studded felt and studded Aquastealth with good results. In fact, since this model's been replaced by Korkers' second generation interlocking sole technology, you may want to consider picking up an extra set or so of soles while you can get them, since one of the main advantages of these boots is that you don't have to toss them out when the sole material's worn out.
Hope you like them as much as I have. The only reason I bought a pair of the second generation was that I put on so much weight



that I had to get a larger size. As I mentioned earlier, the second generation sole is much harder to interchange for me, although I understand they "improved" the interlock because of problems by some
Konvertibles users with their soles coming loose (a problem I never had). My only regret is that I didn't spend the extra money and get the
Guide model like BlueDun was wiser than I to do, but not because the
Crosscurrent model is not good at what it does, it's just that the
Guide has a faster and more customized lacing system, which would be a lot easier for me since time spent bending over messing with lacing strains my already-weak back.
