Thanks Bun; you were a contributor in that original thread I believe, and it seems you have an extensive knowledge of Nike shoes.
I've been trying to find a flat for long distance running (from 10k up to 50k, including trail) and have been having trouble decicing between the Katana Star, Rac3r, Streak XC, and Marathoner.
The Marathoner I've pretty much discounted because other posters said it lacks traction on wet pavement, which we have here all the time (plus I'd wear them on trails during the summer).
Also, since the Katana Star has more cushioning I'd probably pick that over the Rac3r, which leaves the Star and the XC.
I know they're both pretty different, but care to weigh on on what your opinion is?
