Quality.  You won't find others like these!
Get these.  Get these before they become mass marketed off the brand name and someone decides to just make money.  Get these before these great people can't keep up with demand and you have to wait.  Most of all get these because they are the best things you could put on your feet.  The felt?  It's a full 1/4 inch thick.  I opened the package with anticipation and put one on.  Just one.  I forgot for awhile I should put on the other one.  They are on now.  My son saw them and said "now you aren't going to want to wear any othe shoes".....yeah exactly.  They run true to size-I'm between a men's 8.5 and a 9.  I said so (in an email-you get to customize these), they are a tad loose, but will be good with socks.  Also I got the rubber soles-I will wear these for quick errands, nice quality product.  I'm glad I treated myself.
