What insoles are guys running in kenetrek's? I've been breaking in a pair of kenetrek hardscrabbles (probably 80 good miles in) and since I have a normal arch I needed to switch out the stock insoles that were too high. I've been using the sofsole blue ones with the cushy gel at the front. These usually work great since I've had problems with pain at the ball of my foot, but they seem to be lifting me out of the heel pocket and I'm getting slippage. Anyone else have the same experience?
