Very scared until they arrived.  The fit was spot on and my heel supports fit Inside Perfectly.  There Was no Break In Time.  I worked A 6 Hour Shift the first day With no problems.  They ARE COMPLETELY SLIP PROOF.  NOT JUST RESISTANT.  I Recommend these Shoes For tile, wood, or Any Slip surface..  I am a Shoes For crews Supporter, However The company stopped making the shoe I Liked.  These are my new favorite shoe!!!
