Decided to start my own thread so if you have read this before sorry! I have just been for a 6 mile run in my new Rider 7's. At about 5 miles the bottom of my feet started to feel sore. When I got home and looked at my feet there are the beginnings of blisters on the bottom of both forefeet corresponding with the bumps of the innersole. I am really annoyed as I thought I had found my perfect running shoe as the other problems I had seem much better since switching to the Rider. I have done a couple of 3-4 mile runs with no problems. I know I could switch the inners but would this change the workings of the shoe? I have inners from the Nike pegasus, Asics gel cumulus and 2090's should I swap or would a different sock make a difference. Are the 1000 mile blister free socks really that good? Any comments greatly appreciated.
