I watched the Eco Challenge race on "48 hours" last night. Talk about shredded feet!! They had a close up of one poor lady in excruciating pain taking off her running shoes. (she had to be helicopered out) Don't want to start any more debates but you'll never guess what she was wearing. They had a great big N on the side. I know companies love to get free time on T.V. but not that kind!
