I was really impressed how these shoes felt right out of the box.  Very comfortable!!  This is the first Wave Enigma I have tried and really feel that this is a very good running shoe.  I gave them a 4 out of 5 for the reason that I have had some issues with the balls of my feet burning.  The first 10 mile run, I was good until about mile 6, my 16 mile run I was good until about mile 12.  I did see this review by someone else too.  With that being said, the shoes have definitely fixed some other issues I was having with my previous pair of Mizuno shoes.  So I am attempting to figure out the burning issues by changing socks, which has helped.  I think I read in a different review, that they are a heel-strikers heaven.  I would definitely agree!!  In all reality, my rating should be about a 4 3/4.  They are a very good shoe.  I would buy them again; hoping they come out with more colors soon!!
