I am a slight pronator- I found this out after having a gait analysis done last weekend.
I've been wearing nike air pegasus with no support for pronators for about a year, and have had no issues. Previously, I was wearing an asic with light support- and problems with my knees, and blistering on the insole. No amount of breaking in the shoe/foot stopped the blistering on that sensitive skin.
On Saturday, I bought another pair of shoes with light support, believing the problem was the fit of the asics. After a few minutes on the treadmill in the store, they felt pretty good. After 3.5 miles at the gym, I was blistering on the insole again.
Any ideas? I'll be going back to the store for an exchange, likely today. I guess I'm wondering if its a hazard to do so much running in a shoe without support when I'm 'supposed' to have it- or if it fits, wear it?
If anyone can recommend a good running forum that may have more info, that would be great, too!
