A comment by Bryan over in Culver City indicated he had seen the elusive Vibram Five Fingers “Performa.” Bryan said:
I was at sporteve here in Culver City to pick up my KSOs. They had a performa on the display rack. It resembled suede, but more like thin leather.
On further discussion with Bryan, I asked if the model he had seen looked like the Glove, and he confirmed that it did not:
No, not like [the fivefingers Glove] at all. It had the sole like a KSO, but the top was of the thin leather-like material.
This sounds like confirmation of one my suspicions — that the Performa has full-coverage over the top of the foot similar to the KSO while using the same kangaroo-leather of the Glove (which may be another name for the Moc).
