I got the KOs, while they took forever to get to me, I really like them so far. They were cheap (only $40) and they reflect that but they are well worth the money as training shoes. The are really light, and offer good grip. But the advertising was no joke when they said they will be "the best shoe you ever destroyed". I have used them for a little over 3 weeks and I can already wee where strands are starting to stick out and the eyelets will fall out. They haven't actually started falling apart yet, but they aren't exactly the most durable shoe out there. But overall I still am satisfied with the $40 I spent.
