fitdude62 saidSorry endo, but I love nike Free
Almost like running barefoot but with a nice heal support. Go for the 3.0
I can't speak for the Nike Free shoe because I've never worn them... and never will. This whole barefoot running craze is a silly fad that's going to make many knee specialists extremely rich in about 10 years.
But in general, Nike shoes are overpriced and poorly made (in sweat shops no less), and most serious runners say they're not as durable as other brands and will wear out much quicker. This is probably not a problem if you're running 12-16 miles per week. But if you're training for a marathon, you need a sturdier running shoe.
