I bought these shoes because I couldn't find the ZigActivate. It is extremely light. They're still too new to evaluate durability. They run narrow around where the laces start and I can only wear them for a mile or two before having to switch to another pair. I'm hoping that will go away once they're broken in like it did with the Vibe Tech. Also, the back is a little high and rub on the ankle creating a sore.
