These feel amazing.  The cushioning allowed my to complete an Insanity workout with pain-free joints for the first time.  It holds my foot snugly during lateral movement, and my heel stays in place as well.
However, the picture on Amazon shows sort of a sky blue color.  When they arrived, it's more of a teal/bright blue.  It's bright enough that it's almost a deal-breaker on these.  I'm going to try the Asics Landreth 7, since they are very similar in design and they come in a grey/black/red combo.  Hoping I can find a shoe I love as much on the outside as I do on the inside.
