I got these to fill a gap in my rotation. I wish I'd just got a pair of Enigma II or even the original Enigmas.
My feeling is these shoes are a larger fit. They are so roomy I should have got at least half a size smaller.
They're slow. Even on my recovery runs I like to get along at a reasonable pace, these things felt just terrible.
I can easily outpace myself in a pair of Enigmas or heck even Creations which weigh quite a bit more.
Your mileage may vary but for me I would go for a pair of Ronins over these any day.
