Can someone please tell me what 工艺鞋 are？ 工艺鞋

I think this refers to some kind of decorative shoes which are actually never worn, but I'm not sure. Why would you want to buy shoes you never wear?
Well, to be frank, I am afraid you can not find this "工艺鞋" directly in Chinese dictionaries, so you can take this word as a definition which is not very clearly defined. I have searched on line I can show you several pics, they are all called "工艺鞋". However, as you can see, slippers, sandal, boots.... and from manmade to machine made.....  so you can imagine "工艺鞋" basically they are 'shoes'. If you wanna define it more precisely, they are  artistic temperamental shoes. I hope this can help you. I am not an English native speaker, but I tried my best. cheers.
