I came from the mid 80's and look pedals were just coming into being so I was flabergasted when I started riding again and couldn't get shoes with cleats (What kind of pedal do you have? I don't know.. it doesn't matter, does it? Yes it does. Oh well, I have old pedals then...) anywho, I found I had to get new shoes and pedals and they were going to be clipless, so I got some nashbar pedals and shimano shoes. I did ok at first on the ground, got about 200 miles on them. thats fine.. Then I got my rollers down for a day inside. Needless to say I went down about 15 times during that 12 miles on the rollers (you just can't pull out of clipless pedals you HAVE to twist). It took me a week to debruise. After a thousand miles I am better but i still haven't gotten back on those rollers.
