text: Not for running.  These shoes are really cool looking and I received many comments about their look but they didn't last.  I'm a runner and after about 30 - 40 miles, the blades separated from the bottom of the shoe.  I tried to return them but had them for longer than 30 days so I couldn't receive any type of refund.  This really stinks.  I wish I had never purchased these.  Don't buy these if you are a runner.  They won't last at all.
