I've been running in my VFFs for almost a year. I don't know how many miles I have put on them, but I did run White Rock and the Rocky Raccoon 50 mile trail run in them, plus some other races and virtually all my training runs. As you can see, I have about worn them out. The seam along the big toe ripped pretty early on; we'll see if my new pair does the same.
I got the new ones in this flashy red and black color scheme. I'm sure they'll make me run much faster! They're also Sprints. I noticed a couple of minor changes in the stitching, but they're essentially the same.
I still have the Luke's gift cards. I'll be calling them regularly to see about buying some VFF Treks. In the meantime, I'll start wearing out these new Sprints!
