I haven't used super shoes yet, mostly because I don't believe in cheating (that should spawn some comments), so I'm looking for some feedback here. I was standing at mile 24 of Boston today and couldn't help notice that for the sub 3hr field those who were having calf/achilles/foot issues were almost exclusively wearing super shoes. I even saw a guy stop and take off his nike super shoes to try to continue on in just socks! Nike's super shoes seemed to be the main culprit, but perhaps that's just because they are more prevalent than other brands. To be clear, there were also plenty of runners not wearing super shoes and they were not having issues. Anyway, have people experienced more issues while wearing super shoes? Is it worth the risk?
