I'd like to throw in an enthusiastic thumbs-up for the new Ryka Exertion for your shopping! . I'm not sure if Cathe wears them in any of her new workouts, but I have found them to have the closest *feel* to my original Transitions from a few years back.
I do have to note though, if you prefer a wider toe box, these aren't for you.
Of course! And I just bought my Ryka influence from Planetshoes.com about 2 weeks ago! Oh well, I did get 10% off from there. BTW I LOVE my new shoes (I bought the blue/hot pink ones)!
