I love these shoes. I have been trying to transition to a more minimalist shoe from the Triumph 9. The Kinvara 2 was an easy transition and using the CHI Running method, I had no problems going to a lighter shoe. I ran a half-marathon in them and did not notice any difference between the Kinvara and a more cushioned shoe.  They run small so I went with an 8 rather than a 7.5.
