Amazing! I am training for a half marathon and I literally cannot walk around my house barefoot without being in excruciating pain from all the running.  These are like walking on clouds.  I wear them all day and up to my bed, take them off by my bed and put them on first thing in morning. Could not live without.

I am a 7 1/2 and ordered an 8 since I heard they run small and an 8 fits perfectly.  Go up in size when ordering.
