I wanted to try a minimalist shoe and this seemed like an excellent style to start with.  It is extremely light weight and there isn't a ton of arch support, but that doesn't seem to be a problem.  And it is supposed to fit like a sock, but this shoe runs a full size small.  My usual size 7 was so snug that I didn't think that a half size would be enough and I was right.  The 8 at least let me get my foot in and I do not think that a sock would be a good idea.  It would just get all wadded up and that is another story especially for those of us who have mini-meltdowns when our socks are all mucked up in our shoes!  I am a fitness trainer and I usually put in 2 hours or more a day on my own workout so my shoes have to be comfortable and durable.  I am looking forward to running the hard packed sand in Hilton Head later this summer to compare them to my usual outdoor running.
