Lutz, they discontinued these a while ago, I think they've gone from all of the stores. I know we had them at our big sale in May, and that's the last time I saw them.
If you know what size you are, i'd keep an eye out on ebay - for a while there were quite a few pairs listed.
I love them with jeans - kinda like a cool version of converse or vans.
Lutz - have you seen the new ones? They're quite fabulous...
