I experimented with the Nike Free mainly because I found a new pair on sale for only $20. Nike's own website says they're not for every day use. They were supremely comfortable, but so are bedroom slippers, because they give up a lot of support.

I'm a horrible overpronator so they did not work for me even with occasional use. I gave them to my son and they worked fine for him but 16 year olds can wear almost anything.

I bought the Free as a running shoe, not a hiking shoe.
