Vibram Fivefingers - Help
I am the proud owner of a pair of KSOs since last week.
As per the general advice on this forum and elsewhere I've started off pretty slowly with regard to running. Initially just doing 400m then 600 etc.
Today I was doing a 5K on a treadmill - following the advice of set it at 1% incline etc.
I wore my KSOs with a view to doing 1K in them and then changing to my old Nike Free 5.0s. So at 1K changed shoes quickly and continued running. While I was wearing the KSOs my feet and lower legs felt fine, but about 500m into the part wearing the Frees I developed a pain in the left side of my left foot and my calves started to sieze up. I made another 1.5K before stopping in fear of doing proper damage.
I'm wondering whether this is the effect of the KSOs or whether it's that I'm getting used to the KSOs and changing shoes has affected me.
Has anyone else experienced this?
