First of all wandered into the vibram store today and ended up with these.. not sure what kind they are but they are quite comfy and the people at the store were so nice that I bought them. Woops. Merlin approves. Anyway I went for a run this afternoon and decided "Hey let's disregard anything anyone ever told me about these shoes and push for 5 miles" So I did. and now I'm dying. BAD DECISIONS FRAN.
