I purchased the original Nike Free in October 2004. There were two insoles, a 5.0 and a 4.5. The 5 created "hot spots" on my arch, the 4.5 did not, so I tossed the 5 and ran with the 4.5s. I recently bought a new pair of Free s, but there is only a 5.0 insole in the shoe. Does Nike still provide the 4.5 option and someone took it out of the box I bought or am I stuck with the 5.0 insole?
Thanks for your observations.
