Yup, those all belong to Greg. That’s not even all of them!  I couldn’t find my favorite pair of his, which are blue and shiny and look really fast even when he’s not wearing them.
  He explained it to me once.  I guess shoes have to rest and breathe between really long runs, and switching can help prevent over-use, and the race shoes are lighter but the training shoes are more supportive, and probably some of those are still hanging around for yard work…

All I know is he runs a lot, and he runs really fast, and I’m glad he has the shoes to do it without injury! 🙂

I have two pairs, one that were professionally fitted for me at Marathon Sports, and one set that are super cute and purple and really fast looking, and I love wearing.
